Question

How do you graph `y=x^2 - 2`?

Answer 1

Below

Explanation:

`y=x^2-2` is the graph `y=x^2` shifted down by 2 units

Below is `y=x^2` graph{x^2 [-10, 10, -5, 5]}
Below is `y=x^2-2` graph{x^2-2 [-10, 10, -5, 5]}

The general idea is that if you have an equation `y=x^2+a` where a can be any integer, you shift up by a units if a is positive and shift down by a units if a is negative
