Question

Given the function f described by f(x)=x+12, find...
f(0)=
f(-5)=
f(-12)=
f(8)=
f(x+16)=

Answer 1

f(-12)

Answer 2

So you just replace the X with what is in the parenthesis

Answer 3

so f(0)=x+12 i don't understand this problem

Answer 4

replace x with 0 so f(0) =12

Answer 5

You just put in whatever is in parens for the x.

f(0) = 0 + 12 = 12

Answer 6

f(8) = 8 + 12 = 20

Answer 7

etc.

Answer 8

ok pol so i figured those out, how do i do f(x+16)=?

Answer 9

f(x+16)=?
replace x in f(x)=x+12 by (x+16)

f(x+16)= x+16+12
= x +28
