Question

If f(x)=2x and g(x)=x^2-1 which statement is true?

Answer 1

For this case, the first thing we must do is multiply both functions to obtain the desired result.
 We have then:
 f (x) = 2x
 g (x) = x ^ 2-1
 Multiplying we have:
 (f * g) (x) = (2x) * (x ^ 2-1)
 Answer:
 The following statement is correct:
 B. (f * g) (x) = 2x (x ^ 2-1)
