The graphs below display a graph of a total function $y$ on the left, and a graph of the corresponding change $y$ on the right.

What is the change in the value of $y$ change between $x=2$ and $x=3?$

What is the change in the value of $y$ change between $x=2$ and $x=4?$

What is the change in the value of $y$ change between $x=1$ and $x=5?$

For what $x$ is the value of $y$ the largest? If there is more than one value, enter your answer as a comma separated list. $x=$

For what $x$ is the value of $y$ the smallest? If there is more than one value, enter your answer as a comma separated list. $x=$
