Let's take f(x), if we were to say, if we were to transform this function as f(2x), this would be a horizontal shrink by a factor of 1/2 (reciporcal). Similarly, if we took f(1/2x) this would be a horizontal stretch by a factor of 2 (reciprocal)
(If factor is more than 1, then horizontal shrink by the reciprocal of the factor, if factor is mo
