    horizontal stretch/compression factor when graphing functions

    If a function is horizontally stretched by a factor of 1/a, then to graph, I would divide my original x-values in the function by 1/a.

    Is that correct?

    And if my original function is horizontally compressed by a factor of a, I would divide my original x-values by a.

    Is that correct?

    hi

    yes but to make it simpler :

    stretch by a factor of a (times a)

    compressed by a factor of b (divide b)
