Question

HELP ASAP, BIG TEST!
When f(c)= 10x^2 + 3x -4, evaluate f(-4)

Answer 1

`f(x) = 144`

Explanation:

This problem deals with a function. All this question is asking is to plug in -4 every time an x appears.

So, let's do that:

`f(-4) = 10(-4)^(2) + 3(-4) - 4`

`f(-4) = 10(16) - 12 - 4`

`f(-4) = 160 - 16`

`f(-4) = 144`
