Which letters are symmetrical both vertically and horizontally?

write a paragraph explaining the differences between point

and line symmetries.

Graph the following functions and look for lines or points of symmetry.

Define even and odd functions.

Even function – function whose graphs are symmetric with respect to the y-axis [f(x)=f(-x)]

Odd function – function whose graphs are symmetric with respect to the origin [f(-x)=-f(x)]
