Question

How do you sketch the graph of `y=-5x^2` and describe the transformation?

Answer 1

See below :)

Explanation:

The standard `y=x^2` is drawn in blue, the graph of `y=-5x^2` is drawn in red.

The tranformations, in order are as follows;
- Dilation parallel to the y-axis, scale factor 5
- Reflection about the x-axis

I hope that helps :)
