Question

Evaluate the function f (x) = x Over 3 + 4 for f(-9).

Answer 1

`\huge f( - 9) = 1`

Explanation:

`f(x) = (x)/(3) + 4 \\`

To find f(-9) , substitute the value of x that's - 9 into f(x) , that's for every x in f(x) replace it with - 9

We have

`f( - 9) = - (9)/(3) + 4 \\ = - 3 +4`

We have the final answer as

`f( - 9) = 1`

Hope this helps you
