Explanation of Solution

Given information:

The functions, f(x)=2x+3 and h(x)=−3x−12 .

Formula used:

The multiplication or product of the functions f and g is represented as f⋅g , mathematically it is denoted by,

(f⋅g)(x)=f(x)⋅g(x)

Calculation:

Consider the provided functions, f(x)=2x+3 and g(x)=3x−5 .

Recall the multiplication or product of the functions f and g is represented as f⋅g , mathematically it is denoted by,

(f⋅g)(x)=f(x)⋅g(x)

Evaluate the value of f(x)⋅h(x) that is product of the functions,

f(x)⋅h(x)=(2x+3)⋅(−3x−12)

Multiply the first term of the first bracket with the terms in second bracket and do the same with the second term of the first bracket.

f(x)⋅h(x)=(2x+3)⋅(−3x−12)=2x(−3x−12)+3(−3x−12)=−6x2−24x−9x−36

Combine the like terms,

f(x)⋅h(x)=(2x+3)⋅(−3x−12)=2x(−3x−12)+3(−3x−12)=−6x2−24x−9x−36=−6x2−33x−36

Therefore, the value of product of the function is −6x2−33x−36 .

Now, evaluate the value of the individual function f(x)=2x+3 , h(x)=−3x−12 and product of the function, f(x)⋅h(x)=−6x2−33x−36 at the provided points x=−2,x=−1,x=0,x=1 and x=2 .

For x=−2 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=6x2−x−15 .

f(−2)=2(−2)+3=−4+3=−1

Next,

h(−2)=−3(−2)−12=6−12=−6

Last,

f(−2)⋅h(−2)=−6(−2)2−33(−2)−36=−24+66−36=6

For x=−1 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=−6x2−33x−36 .

f(−1)=2(−1)+3=−2+3=1

Next,

h(−1)=−3(−1)−12=3−12=−9

Last,

f(−1)⋅h(−1)=−6(−1)2−33(−1)−36=−6+33−36=−9

For x=0 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=−6x2−33x−36 .

f(0)=2(0)+3=3

Next,

h(0)=−3(0)−12=−12

Last,

f(0)⋅h(0)=−6(0)2−33(0)−36=−36

For x=1 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=−6x2−33x−36 .

f(1)=2(1)+3=2+3=5

Next,

h(1)=−3(1)−12=−3−12=−15

Last,

f(1)⋅h(1)=−6(1)2−33(1)−36=−6−33−36=−75

For x=2 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=−6x2−33x−36 .

f(2)=2(2)+3=4+3=7

Next,

h(2)=−3(2)−12=−6−12=−18

Last,

f(2)⋅h(2)=−6(2)2−33(2)−36=−24−66−36=−126

Thus, the above results are tabulated as,

xf(x)h(x)( f⋅h)(x)−2−1−66−11−9−903−12−3615−15−7527−18−126

Plot the graph of the functions f(x)=2x+3 , h(x)=−3x−12 and (f⋅h)(x)=−6x2−33x−36 on the same coordinate axes and visualize the each of them.

Explanation of Solution

Given information:

The functions, f(x)=2x+3 and h(x)=−3x−12 .

Formula used:

The multiplication or product of the functions f and g is represented as f⋅g , mathematically it is denoted by,

(f⋅g)(x)=f(x)⋅g(x)

Calculation:

Consider the provided functions, f(x)=2x+3 and g(x)=3x−5 .

Recall the multiplication or product of the functions f and g is represented as f⋅g , mathematically it is denoted by,

(f⋅g)(x)=f(x)⋅g(x)

Evaluate the value of f(x)⋅h(x) that is product of the functions,

f(x)⋅h(x)=(2x+3)⋅(−3x−12)

Multiply the first term of the first bracket with the terms in second bracket and do the same with the second term of the first bracket.

f(x)⋅h(x)=(2x+3)⋅(−3x−12)=2x(−3x−12)+3(−3x−12)=−6x2−24x−9x−36

Combine the like terms,

f(x)⋅h(x)=(2x+3)⋅(−3x−12)=2x(−3x−12)+3(−3x−12)=−6x2−24x−9x−36=−6x2−33x−36

Therefore, the value of product of the function is −6x2−33x−36 .

Now, evaluate the value of the individual function f(x)=2x+3 , h(x)=−3x−12 and product of the function, f(x)⋅h(x)=−6x2−33x−36 at the provided points x=−2,x=−1,x=0,x=1 and x=2 .

For x=−2 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=6x2−x−15 .

f(−2)=2(−2)+3=−4+3=−1

Next,

h(−2)=−3(−2)−12=6−12=−6

Last,

f(−2)⋅h(−2)=−6(−2)2−33(−2)−36=−24+66−36=6

For x=−1 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=−6x2−33x−36 .

f(−1)=2(−1)+3=−2+3=1

Next,

h(−1)=−3(−1)−12=3−12=−9

Last,

f(−1)⋅h(−1)=−6(−1)2−33(−1)−36=−6+33−36=−9

For x=0 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=−6x2−33x−36 .

f(0)=2(0)+3=3

Next,

h(0)=−3(0)−12=−12

Last,

f(0)⋅h(0)=−6(0)2−33(0)−36=−36

For x=1 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=−6x2−33x−36 .

f(1)=2(1)+3=2+3=5

Next,

h(1)=−3(1)−12=−3−12=−15

Last,

f(1)⋅h(1)=−6(1)2−33(1)−36=−6−33−36=−75

For x=2 , substitute the value of x in the functions, f(x)=2x+3 , h(x)=−3x−12 and f(x)⋅h(x)=−6x2−33x−36 .

f(2)=2(2)+3=4+3=7

Next,

h(2)=−3(2)−12=−6−12=−18

Last,

f(2)⋅h(2)=−6(2)2−33(2)−36=−24−66−36=−126

Thus, the above results are tabulated as,

xf(x)h(x)( f⋅h)(x)−2−1−66−11−9−903−12−3615−15−7527−18−126

Plot the graph of the functions f(x)=2x+3 , h(x)=−3x−12 and (f⋅h)(x)=−6x2−33x−36 on the same coordinate axes and visualize the each of them.

Explanation of Solution

Given information:

The functions, f(x)=2x+3 and h(x)=−3x−12 .

Formula used:

The multiplication or product of the functions f and g is represented as f⋅g , mathematically it is denoted by,

(f⋅g)(x)=f(x)⋅g(x)

Calculation:

Consider the provided functions, f(x)=2x+3 and g(x)=3x−5 .

Recall the multiplication or product of the functions f and g is represented as f⋅g , mathematically it is denoted by,

(f⋅g)(x)=f(x)⋅g(x)

Evaluate the value of f(x)⋅h(x) that is product of the functions,

f(x)⋅h(x)=(2x+3)⋅(−3x−12)

Multiply the first term of the first bracket with the terms in second bracket and do the same with the second term of the first bracket.

f(x)⋅h(x)=(2x+3)⋅(−3x−12)=2x(−3x−12)+3(−3x−12)=−6x2−24x−9x−36

Combine the like terms,

f(x)⋅h(x)=(2x+3)⋅(−3x−12)=2x(−3x−12)+3(−3x−12)=−6x2−24x−9x−36=−6x2−33x−36

Therefore, the value of product of the function is −6x2−33x−36 .
