Question

How do you sketch the graph of `y=x^2-3` and describe the transformation?

Answer 1

See explanation.

Explanation:

The graph of `y=x^2-3` is a vertical shift, 3 units down, of the graph of `y=x^2`. Start with the graph of `y=x^2`, which is definitely worth memorizing if you haven't already, and shift the entire graph down 3 units.
