Expert Solution & Answer
Check Mark

Answer to Problem 1RE

Solution:

From left to right, if the slope of the function is negative, then it is decreasing and if the slope of the function is positive, then it is increasing.

Explanation of Solution

A function is positive when its graph moves upwards and a function is negative when its graph moves downwards. When the slope of a graph is positive, it moves upwards. When the slope of a graph is negative, it moves downward.

Thus, if the slope of the graph of a function is positive then it is increasing and if the slope of the graph of a function is negative, then it is decreasing.
