If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g –
2 answers:
F(x) = 4 - x^2
g(x) = 6x
(g - f)(x) = g(x) - f(x) = 6x - (4 - x^2) = 6x - 4 + x^2
(g - f)(3) = 6(3) - 4 + 3^2
Answer:
Option (c) is correct.

Step-by-step explanation:
Given : 
We have to find the expression is equivalent to (g –f)(3)
That is g(3) - f(3)
First find g(x) - f(x)
We have,

Now, put x = 3
We have,

Thus,
