For the first interval (-1, 2), f(-1) = f(2), which means that the average rate of change on that interval is zero, so the correct option is A.
<h3>
Over which interval the rate of change is zero?</h3>
For a function f(x) we define the average rate of change over the interval (a, b) is defined as:
R = (f(b) - f(a))/(b - a)
Here the function is:
f(x) = x^2 - x -1
And the rate of change will be zero on an interval (a, b) if and only if:
f(b) = f(a).
Notice that the first interval is (-1, 2)
f(-1) = (-1)^2 - (-1) - 1 = 1 + 1 - 1 = 1
f(2) = 2^2 - 2 - 1 = 4 - 2 - 1 =1
Then f(-1) = f(2), which means that the average rate of change on that interval is zero, so the correct option is A.

Yeah its D i just checked
The question is an illustration of the Truth in Lending Act, and Dan is responsible for paying $0
<h3>Truth in Lending Act</h3>
The Truth in Lending Act is simply an act that protects people from unfair charges on their credit cards, especially in case of theft and card misplacement.
<h3>The scenarios</h3>
From the question, we have the following scenarios
- His card got lost
- He reported
- Someone else saw the card and purchased goods worth over $200
Because Dan reported when his card got lost, he is protected by the Truth in Lending Act (TILA).
Hence, Dan is responsible for paying $0
