You can use the distance equation.. d = rt
d = distance = 645
r = rate = 215 mph
t = time = ???? find the time
645 = 215t
645/215 = 215t / 215
3 = t
t = 3
It took 3 hours

Given that ƒ(x) = x2 + 1 and g(x) = –3, multiply the functions (g · ƒ)(x). Question 8 options: A) (g · ƒ)(x) = –3x2 – 3 B) (g ·
vesna_86 [32]

Answer:

A

Step-by-step explanation:

We are given the two functions:

f(x)=x^2+1\text{ and } g(x)=-3

And we want to find:

(g\cdot f)(x)

This is equivalent to:

=g(x)\cdot f(x)

Substitute:

=(-3)\cdot (x^2+1)

Distribute:

=-3x^2-3

Therefore:

(g\cdot f)(x)=-3x^2-3

So, our answer is A.
