Question

How do you graph `f(x) = |x| + 4`?

Answer 1

You will have to make two graphs, depending on wheter `x` is negative or not:

Explanation:

`x<0`
The absolute bars will make it positive, so in fact we are now looking at `f(x)=-x+4`

`x>=0`
Nothing needs to be do, so it's `f(x)=x+4`
graph{|x|+4 [-13.86, 14.62, -3.23, 11.01]}
