## Algebra 1: Common Core (15th Edition)

The graph of $y=x^3$ is graphed below and to graph the function $y=3x^3$ we stretch the graph vertically by a factor of three. For each x-value, we multiply each y-value times 3. So for example, the point (1,1) of function $y=x^3$ becomes (1,3) for the function $y=3x^3$ as the y-value is 3 times.
