Question

Evaluate the function for the given value of x. If you can explain how you got the answer that would be great! :D

f(x) = -6x2 - 4x - 4 , x = - 2

Answer 1

directly put x=-2
f(-2)= -6 (-2)^2 -4(-2) -4

now (-2)^2 = (-2)(-2) =4
4(-2)=-8
so, f(-2) =-6(4)-(-8)-4
=-24+8-4
i think u can solve further
