Part A Question (#1)

Answer 1

The slope of the secant line is the same thing as the average rate of change.

The average rate of change from an interval from
`x_1` to
`x_2` is the change in the value of the function divided by the change in x.


`(f(x_2)-f(x_1))/(x_2-x_1)`

Let's find the values of
`f(x_1)` and
`f(x_2)`


`f(x_1)=570`

`f(x_2)=1198.8`


`(f(x_2)-f(x_1))/(x_2-x_1)`


`= (1198.8-570)/(4-0)=157.2 \approx 157`

Your answer rounded to the nearest whole number is 157.
