Question

How do you graph `Y=(x+3)^2`?

Answer 1

It's just `y=x^2` moved three times to the left

Explanation:

Any number thats subtracted or added in a parenthesis with `x` changes the way the graph is
If you have `y=(x+3)^2` the graph is going to get moved three times to the left and if it's `y=(x-3)^2` the graph is going to get moved three times to the right.
As for graphing just pick a `x` value like `3` and plug it in
`y=((3)+3)^2` or `y=36`
You know the graph is going to start at (-3,0) as I explained above so just keep picking `x` values to get a more accurate graph.
