Question

The function f(x) is graphed below. In two or more complete sentences, describe how to find the interval(s) where the function is decreasing and how interval notation is used to express the interval(s). In your final answer, include the interval in which the function is decreasing.

Answer 1

Answer:

The way that I learn is that say you have a car going from the left to the right. Wherever the car goes down is where it decreases. You use the x values. Therefore you start just after -5 and you end at 0. Therefore the answer would be that the function is decreasing at (-5,0] .
