If g(x)= -4x^2-3x+2, determine g(-2)?

If g(x)= -4x^2-3x+2, determine g(-2)?
Algebra 1, August 2019 Regent exam
Answer and Explanation:
We have a function g of x, where x can be any number or variable. To calculate g(-2), all we need to do is to plug in -2 in the equation everywhere we see x.
Therefore, this equation becomes g(-2)= -4(-2)^2-3(-2)+2 = -4(4)+6+2= -8
The answer for this problem is -8
Hint: Every time we have a function such as g(x) and are asked to calculate g of something, we just plug that something instead of x.
