1-8.

The graph for part (d) of problem 1-7 is different from the other three graphs.

1. Explain how the graph is different from the other three graphs.

What do the other three graphs have in common?

2. What in the equation for part (d) makes its graph different?

What is different about $x$?

3. What is the graph for part (d) called?

a parabola

4. What are the domain and range of the function for part (d)?

Are there any values for $x$ that have no output?
What are the possible outputs ($y$-values)?
