Question

How do you use the important points to sketch the graph of `y=-2x^2`?

Answer 1

Upside down 'U' shape

Explanation:

If you make x = 0, you will find the y intercept (0). There is not a lot else you can glean from this equation on a sketch without putting some values on the axes. It's just a bit steeper than `y=-x^2`.
