1.? Katie is deciding how to divide her time between two jobs: the first one is a wedding photographer, and as long as she does this job, she can earn $27 an hour; The other is as a fossil collector. The reward of this job depends on the quantity and value of fossils she finds. In addition to the income difference between the two jobs, the number of fossils found by Katie also depends on the time she spends every day, as shown in the following table:

The time spent every day and the number of fossils found every day.

a.? Draw a table, the first column is the dollar price, increasing from 0 to 30; The second column is the number of fossils Zoe is willing to provide every day at this price.

b.? Draw each set of data in the above table as a point into a coordinate axis, with the price as the vertical axis and the number of fossils provided every day as the horizontal axis, and connect the points to form a curve. What's the name of this curve?

I probably did it, but I may have done it wrong, as shown in the figure: the two columns on the left are the table made, and the graph on the right is the coordinate axis. This parabola is called a parabola.
