You can put this solution on YOUR website!
Side Note: this is NOT a slope equation.

I'll do the first part to start you off

The idea is to plug in the given number and evaluate

a)
f%28x%29=x%5E2%2B3x-2

f%28-2%29=%28-2%29%5E2%2B3%28-2%29-2 Replace 'x' with -2

f%28-2%29=4%2B3%28-2%29-2

f%28-2%29=4-6-2

f%28-2%29=-4

So the answer to part a) is f%28-2%29=-4
