Answer :
Option (c) is correct
Step-by-step explanation:
Given : functions
and
We have to calculate (fg)(x) and choose the correct from the given options.
Consider (fg)(x) = (f • g)(x) = f(x) • g(x)
That is we have to multiply the two functions.
Consider the given functions
and
Then,
Multiply the each term of first bracket with each term of second bracket, we have,
Simplify, we have,
Thus,
Option (c) is correct.
