Question

F(9) if f(x) = x - 8

Answer 1

f(9)=1

Explanation:

f(x)=x-8

plug in 9for x

f(9)=9-8

9-8 =1

Answer 2

f(9)=1

Explanation:

This questions asks us to find f(9).

It is asking us to find what f(x), or y is, when x is equal to 9.

f(x)=x-8

Therefore, we can substitute 9 in for every x.

f(9)=9-8

Subtract 8 from 9

f(9)=1

If f(x)=x-8, then f(9)=1
