If a graph of a function has a line of symmetry, the function be even about line. This means that if the function is transformed so that the line becomes the y axis, we will be able to writewherefor some number

Supposeshown below.

The graph has a vertical line of symmetry with equation

Suppose we writethenso that the lineis the line

Write thenandis even sooris a line of symmetry.
