2-109.

For each of the following equations, describe how d transforms the parent graph. Homework Help ✎

1. $y=dx^3$

Notice that d is being multiplied.

It compresses or stretches the graph.

2. $y=x^2−d$

Notice that d is being subtracted.

It shifts the graph up or down.

3. $y=(x−d)^2+7$

Notice that d is being subtracted from x.

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