If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)? a.6 – 3 – (4 + 3)^2 b,6 – 3 – (4 – 3^2) c.6(3) – 4 + 3^2 d.6(3) – 4 – 3^2

Remember that  is . We know form our problem that  and , so:




Now, to find , we just need to evaluate  at 3. In other words, we are going to replace  with 3:



We can conclude that the correct answer is C.6(3) – 4 + 3^2
