Question

Describe how to determine the average rate of change between x = 1 and x = 3 for the function f(x) = 3x^3 + 1. Include the average rate of change in your answer.

Answer 1

You just need to work out the values of f(1) and f(3), then divide the difference in f(3) and f(1) by the difference of 3 and 1

Answer 2

That is:\[(f(3) - f(1))/(3 - 1)\]

Is this the one in your question?

Answer 9

Can you find f(3) and f(1)?

Answer 10

Substitute x with 3 or 1 in the given equation.
f(3) = 3*3^3 + 1
f(1) = 3*1^3 + 1
