Question

If f(x) = x - 5, what is the value of f(8)? -13 -3 3 13

Answer 1

3

Explanation:

We must plug in 8 into the equation of the function since f(x) = x - 5 for all values of x. Since 8 could be a value of x, we can plug it in:

`f(8) = 8-5`

The value of 8 minus 5 is 3, so the value of f(8) is 3.

Answer 2

putting the value of X=8 in f(X)

f(8)= 8-5

f(8)= 3
