does the graph look like a U? and anything else you can do to help explain it.

x^2 is a parabola, or a U as you described it. The coefficient 2 makes the U skinnier, or the sides more steep, however you want to word it. if it were 1/2x^2 it would be very wide and not "steep". Hopes this Helps.

Yes, the graph does look like a U, kinda, except that it's sides are steeper than y=x^2 so it would kind of look like a curved out V. You can use an online calculator that I looked up for you. Just type in the 2x^2 and click Eval on the calculator and you get a picture of that graph. Click on the "Source" site that I put below this to go to the online calculator @ coolmath.com. Hope this helps.

If you don't have a graphing calculator, you can make your own graph by findiny y for certain values of x and plotting them on a graph.
For example:
x=1, y=2
x=2, y=8
x=3, y=18
If you plot these points, you will be able to see the shape of the graph which will look like a U.

when looking at y=2x^2 notice the x is squared, so whatever value x has the y result will be positive. this means all values will plot on the upper half of the graph and the pts will reflect across the y-axis. the following website is a great place to check your work.

look into geometry and xy-plots. the page with graph of your eqn is linked below

Graphing calculator Yes, it looks like a U. The lowest point goes through the X and Y axis right at 0 where they meet.
