## Problem 10

In this problem we have to look at the multiple choice answers first. There are points mentioned:

For , the slope of the function would be negative. Therefore, and option is incorrect.

For , the slope of the function would be negative. Therefore, and option is correct, while option is wrong.

It is still a good idea to double check that other options do not apply.

For , the slope of the function would also be negative. Therefore, and option is incorrect.

The right answer is .
