Given f(x) = x +1, g(x) = 2x, h(x) = x3 what is (f º g º h)(x)?

Step-by-step explanation:

Given f(x) = x +1, g(x) = 2x, h(x) = x3

What is (f º g º h)(x)?

2x3 + 1

8x3 + 9x + 1

8x3 + 12x2 + 6x + 1

8x3 + 24x2 + 24x + 8

First one is A.  

(h º g º f)(x)?

2x3 + 1

8x3 + 9x + 1  

8x3 + 12x2 + 6x + 1

8x3 + 24x2 + 24x + 8

Second one is D.

see attached graph

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
