Question

How do you graph `y=sqrt(x-4)` and compare it to the parent graph?

Answer 1

See below:

Explanation:

First, graph the parent graph: `y=sqrtx`:

graph{sqrtx [-1.79, 18.21, -1.32, 8.68]}

Now, the `-4` on the inside signifies that you move the graph to the right 4 spaces. So the graph of `y=sqrt(x-4)` will look like:

graph{sqrt(x-4) [-1.79, 18.21, -1.32, 8.68]}
