Answer:
g(n) = 2n^2 - 4n; Find g(-9)
The answer is 170, because you have to plug in -9 for all the N values. When you do that, just follow PEMDAS.
P-Parentheses
E-Exponents
M-Multiplication
D-Division
A-Addition
S-Subtraction
Explanation:
g(-9) = 2(-9)^2 - 4(-9)
g(-9) = 18^2 -4(-9)
g(-9) = 134+36
g(-9) = 170
I really hope this helps!
