Question

How do you graph `y=sqrt(x)-4`?

Answer 1

See explanation

Explanation:

The graph of `y=sqrt(x)-4` is simply the graph of `y=sqrt(x)` shifted down `4` units

First let's look at the graph of `y=sqrt(x)`
graph{sqrt(x) [-10, 10, -5, 5]}

Then, in order to get the graph of `y=sqrt(x)-4` we shift the entire function down `4` units. Algebraically speaking, we subtract `4` from each `x`-value and replot the function. The end result is then this graph of `y=sqrt(x)-4`
graph{sqrt(x)-4 [-10, 10, -5, 5]}
