4-93.

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 streches the graph

1. $y = 3x^{2} − d$

Notice that d is being subtracted.

It shifts the graph up or down.

1. $y = \left(x − d\right)^{2} + 7$

What kind of graph does this equation represent?

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

See part (b).
