2-109.

For each of the following equations, describe how $d$ transforms the parent graph.

1. $y=dx^3$

Notice that $d$ is being multiplied.

It compresses or stretches the graph.

1. $y=x^2−d$

Notice that $d$ is being subtracted.

It shifts the graph up or down.

1. $y=(x−d)^2+7$

Notice that $d$ is being subtracted from $x$.

1. $y=\frac{1}{x}+d$
