Symmetry creates the visual effect of putting a mirror in the graph of the equation.

'; explain[1] = '#2

The different types of symmetry are y-axis, x-axis, and origin. There are 3 types of symmetry.

'; explain[2] = '#3

2 of the 3 types of Symmetry are axis symmetry the third is origin symmetry. There is only 1 type of symmetry that is non axis.

'; explain[3] = '#4

Graphs that are symmetric to the y-axis are even functions (the term even comes from the highest power used in the function)

'; explain[4] = '#5

Streching and shrinking graphs is a fairly simple process, you just have to know what part of the equation to multiply or divide.
