QUESTION~
For the function in Item 2, what is
the average rate of change over
the interval 2 ≤ x ≤ 3?
A.(0)
B.(1)
C.(5)
D.(25)

Answer 1

See below.

Explanation:

You don't show what the function is, but I'll explain how to do it.

The average rate of change of function f(x), from x = a to x = b, is given by the fraction:

`(f(b) - f(a))/(b - a)`

Since I don't know what the function is, I cannot evaluate the function at x = a and at x = b, which in your case are x = 2 and x = 3, but you can do it.

Here are the steps you need to do:

1) Evaluate the function at x = 3. Get a value for f(3).

2) Evaluate the function at x = 2. Get a value for f(2).

3) Evaluate the following fraction, after writing the values for f(3) and f(2) that you found in steps 1) and 2) above.

`(f(3) - f(2))/(3 - 2)`

The denominator above is easy. It's just 1.

Try it and see what you get. You can write the function and your answer in the comments if you need more help.
