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 – 32)

c) 6(3) – 4 + 32

d) 6(3) – 4 – 32

 The correct option is

(C)

Step-by-step explanation:  We are given two functions f(x) and g(x) as follows :

We know that for any two functions p(x) and q(x), we have

Therefore, we get

Thus, (C) is the correct option.
