What is the resulting ordered pair if the value of the independent variable is 2?

f(x)=-6x^3 -4x^2

A. (–52, 2)
B. (2, –64)
C. (2, –52)
D. (–64, 2)

To find f(2), put 2 where the variable is, then do the arithmetic. It might be easier to factor out x^2:
  f(x) = (-6x-4)·x^2
  f(2) = (-6·2-4)·2^2
  = -16·4
  = -64

Then the ordered pair (x, f(x)) for x=2 is
  B. (2, -64)
