Hello, camherokid!

Describe at least two ways the graph changes asachanges.

. . y .= .½[e^{-x/a} + e^{x/a}]

The curve is called acatenary,which resembles a parabola.Code:* | * | * | * * | * * | * * | * * | - - - - - - + - - - - - - |

As|a|gets larger, the graph gets "wider".

. . There is a horizontal dilation.

As|a|gets smaller, the graph gets "narrower".

. . There is a horizontal compression.
