Answer:
D h(x) = f(x)×g(x)
Step-by-step explanation:
h(x) has a wave with 2 changes in direction.
so, this needs to be an expression of the third degree (there must be a term with x³ as the highest power of x).
and that is only possible when multiplying both basic functions. all the other options would keep it at second degree (x²) or render it even to a first degree (linear).
Answer:
the 2nd one is the answer.
x ≥ −8

Hope that helps
Sorry if wrong
Answer:
3.5 hours
Step-by-step explanation:
You are trying to isolate X (get X by it self) to do that you need to divided both sides of the equation by 60 resulting in X=3.5
