Question

Find the average rate of change of h (x)=2x squared-7x from x=1 to x=5. Simpifily your answer as much as possible.

Answer 1

h(x) = 2x^2-7x
the average rate of change is just the slope of the line from (1,h(1)) to (5,h(5)). That is,

(h(5)-h(1))/(5-1)

Answer 2

The answer has to be a simplified whole number

Answer 3

So go ahead and simplify the expression that Steve gave you.
