Question

How do you graph `y=2sqrt(x-3)`?

Answer 1

See the graph and explanation.

Explanation:

`y=2sqrt(x-3)>=0, with x>=3`

This is derived from the ( parabola ) equation

`y^2=4(x-3)`, for the upper half of the parabola.

The lower half is given by

`y^2=-2sqrt(x-3)`

graph{y-2sqrt(x-3)=0 [-20, 20, -10, 10]}
