Question

How do you evaluate the function when x = -3, 0, and 2 for f(x) = 15x + 4?

Answer 1

Shown below

Explanation:

For each of the values of `x` simply plug in that value in `f(x)`

Hence when `f(x) = 15x +4` and you put `x = -3`

We get `f(-3)` then just replace each `x` in the expression you see with `-3`

`=> f(-3) = 15(-3) +4 = -45 +4 = -41`

`=> f(0) = 15(0) +4 = 0 +4 = 4`

`=>f(2) = 15(2) +4 = 30 + 4= 34`
