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

f (9) = 1

Step-by-step 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

f (9) = 1

Step-by-step explanation:

f (x) = x-8

plug in 9for x

f (9) = 9-8

9-8 = 1
