Find functions f and g so that h(x) = (f ∘ g)(x). h(x) = (6x - 14)8

Natalija [7]

$h(x)=(6x-14)^8=[g(x)]^8\\\\f(x)=x^8\\\\g(x)=6x-14\\\\(f\ \circ\ g)(x)=(6x-14)^8$

Write and graph an equation in two variables that shows the relationship between the time t and the distance d traveled.

wolverine [178]

Well wouldnt d just be 660 miles?
This would be a line graph with the initial point (0,0) and a point (660,10). Using rise/run, the slope of the line is 660/10 which is 66.
