Chapter 4.1, Problem 111E

To determine

$\left(a\right)$ If the given graph is even or odd function.

$\left(b\right)$ The average temperature in August, if June corresponds to $x=-1$ and August to $x=1$ and the average temperature in June is ${83}^{\circ }\text{F}$.

$\left(c\right)$ If March corresponds to $x=-4$ and November to $x=4$, then by the graph, how do their average temperatures compare.

$\left(d\right)$ The type of symmetry implies about average temperatures in Austin.
