Question

Evaluate the function

Answer 1

`f (-4) = 20`

`f (6) = 40`

Explanation:

We are given the following function and we are to evaluate it at the two values f(-4) and f(6):

`f ( x ) = x^(2) + 4`

Substituting the given values in place of x in the function:

`f (-4) = (-4) ^2 + 4 = 16 + 4 = 20`

`f (6) = 6 ^2 + 4 = 36 + 4 = 40`

Answer 2

a. f(-4)=20

b. f(6)=40

Explanation:

f(x)=x²+4

Evaluate the function at the given value of the variable:

a. x=-4→f(-4)=(-4)²+4→f(-4)=16+4→f(-4)=20

b. x=6→f(6)=(6)²+4→f(6)=36+4→f(6)=40
