Question

i need you to solve this problem like the example in the second photo

If f(x) = 5x2 + x – 6, find the following:
(a) f(-1) =
(b) f(1) =
(c) f(-2) =

Evaluate f (6) for the function f (x).
f (x) = 2x2 + x – 7
Solution
Our goal is to find the function's value when x is equal to 6. To do this, we need to replace every x with
the value 6. When evaluating a function it is helpful to place parentheses around the value that is being
substituted.
f (x) = 2x? + x – 7
This is the original function.
f) = 2( )? + ()-7
f(6) = 2(6)² + (6) – 7
Remove x's and put parentheses instead
Inside each parentheses write the value of
f(6) = 2(36) + 6 – 7
6
f(6) = 72 + 6 - 7
Evaluate using PEMDAS
f(6) = 78 – 7
f(6) = 71

Expert Solution

Step 1

${f (x) = 5 x}^{2} + x - 6 f () = 5 {()}^{2} + () - 6 [R e m o v e x' s a n d p u t p a r e n t h e s e s i n s t e a d]$

a) f(-1)

$f (- 1) = 5 {(- 1)}^{2} + (- 1) - 6 f (- 1) = 5 \times 1 - 1 - 6 f (- 1) = 5 - 1 - 6 f (- 1) = 4 - 6 f (- 1) = - 2$
