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

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,

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
