If f(x)=8x^3-6x^2+x-3 and g(x)=0, find (f o g)(x) and (g o f)(x)

(f o g)(x) = -3

(g o f)(x) = 0

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.
