Answer 1

-1

Explanation:

They give you an x value to plug in, just like with any equation, any time you see a letter and they give you the value to that letter. Replace the letter with the numerical value. The letter in other words is just a placeholder until you know the value.

`5(-2)^3+8(-2)^2-3(-2)+1=-1`
