Question

f(x) = x + 2 g(a) = 3.02 – 5 Find (f.g)(x). O A. (fºg)(x) = 3x3 + 6x2 + 5x + 10 B. (f.g)(x) = 3x3 – 10 O c. (fºg)(x) = 3x3 + 6x2 – 5x – 10 O D. (f.g)(x) = 3x3 + 10

Answer 1

EXPLANATION

Given the function:

f(x) = x + 2

g(a)= 3x2 - 5

We need to find the value of f.g(x) as follows:

(f.g)(x)=(x+2)*(3x2-5)= 3*3 + 6*2 -5x - 10

So, the right answer is the option C.
