f(x) = - 2 x² - 4 for x = 3

f(3) = - 23² - 4

f(3) = -29 - 4

f(3) = -18 -4

f(3) = -22

Answer D

hope this helps!

SyntaxError

\(f(x) = -2x^2-4 \\ f(x) = -2(3)^2-4 [tex][plug in 3 into your x value][tex]\\ f(x)=-18-4[tex] [3 squared equals 9. Now multiply 9*(-2) = -18[tex]\\ f(x)=-22 [ -18-4]\)
