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
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
the 20 has a negative sign its not positive
Okay yeah I see I was like It can't be positive 20. :D
Yes I do actually thats why I was like this can't be positive 20 lol
ok, great. Just wanted to make sure before I left this area. =)
