Tell whether the function is quadratic. Y+5=2X^2 How would you solve this?

Question

Tell whether the function is quadratic.                                                                                                                                              Y+5=2X^2                                                                                                                                            How would you solve this?

If you put it into vertex form, it would look like this:  y = 2x^2 - 5.  The 2 out front makes the graph closer to the y axis than it would if it was not there.  The ^2 part means it's a quadratic function, and the -5 moves the whole graph down 5 units on the y axis.  You would not really be solving it, per se, but just to maybe put it into vertex form and then graph it from a chart.
