Q: If g(x)=4x/3, find g(4)

A: To solve these type of equality just put the value in the function then you will get your answere

Q: 21 If f(x) = x - 4x + 2, simplify each of f(x + h) = f(x + h)- f(x) = %3D

A: For f(x+h) put x+h at x

Q: If E[X] = −3 and Var(X) = 5, then E[(5 + 6X)²] = and Var(3 + 5X) =

A:

Q: Given the functions f (x) = 3x + 5 = (x) 6 g (x) = 4 – x2 and h (x) = = 1 *, find each of the -…

A:

Q: If f(x)-x2 for all real numbers, what is f-1 for x>4?

A:

Q: If f(x) = x3 + 1, then give the following

A: Consider the function: fx=x3+1

Q: if h(x)=x2-6, find h-1(x)

A: To find the inverse of the function, use the below steps. Replace h(x) by y, so we get y = x2 - 6

A:

Q: If f(x) = 2 + 2, g(x) = a 9 and h(a) = VT, then %3D f(g(h(x)))= (no need to simplify)

A:

Q: Suppose ​f(x)=​2.7(x−​2015)+35 models a situation where x represents a year. If we would like to…

A:

Q: if g(x) =3+ x+ e x , find g -4

A: g(x)=3+x+exTo find: g-4

Q: If f(a) x* + 5, g(a) =-6 and h(z) a, then

A: Given: To find:

Q: For each year, t, the population of a forest of trees, call it Forest A, is represented by the…

A: A(t)=85(1.026)t B(t)=113(1.021)t C(t)=123+(2.3)t

Q: If f(14)=27, find f-1(27)

A: If f(x) = y is any function and f is one-one then, => f-1(y)=x

Q: What happens to the value g(x) if x is tripled

A: The value of the function when the x value is changed, totally depends upon the type of function.
