Find for the following functions. f(x) = 12x2 + 7x + 2 g(x) = 9x + 7
12x2 + 16x + 2
21x3 + 14x + 2
12x2 + 16x + 9
21x2 + 14x + 2

I Believe your answer is 12x2+16x+9

if not, be more specific for what you need, I will be glad to answer

Step-by-step explanation:

One of the following functions is made of a composition of f(x) and g(x)

12x2 + 16x + 2

21x3 + 14x + 2

12x2 + 16x + 9

21x2 + 14x + 2

If we sum f(x) with g(x) we have the answer 12x2+16x+9

Perfoming another operation like f(x)*g(x), f(x)-g(x), f(g(x)), doesnt give anything like the below functions.
