Describe how to determine the average rate of change between x = 2 and x = 4 for the function f(x) = 2x3 + 1. include the average rate of change in your answer.

56

Step-by-step explanation:

The average rate of change is the slope of the line between the points (2, f(2)) and (4, f(4)).

m = (f(4) − f(2)) / (4 − 2)

m = (2(4)³ + 1 − 2(2)³ − 1) / 2

m = (128 + 1 − 16 − 1) / 2

m = 56

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
