a) an even function is a function for all values of the input $f(-x) =f(x)$ . Thus the graph is symmetric about the y axis and some examples are $y=x^2-2$ and $y= |2x|-3$.
b) An odd function is a function for all inputs $f(-x) = -f(x)$. The graph is symmetric with respect to the origin and some examples include $y=x$ and $\sqrt[5] x$
