You should know the graph of the following basic functions

a horizontal stretch, the y intercept is unchanged. Example: Starting with f 1(x) = x3, we can obtain f 2(x) = f 1 1 2 x = 1 2 x 3. The graph of 1 2 x 3 is the graph of x3 stretched by a factor of 2 horizontally. 1 2 x 3 x3 Again, pay attention to the fact that, in a horizontal stretch/compression that, ................
