Question

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

Answer 1

See below

Explanation:

Consider `f(x)=|x|`

This is of general shape `vv` with the vertex at `(x,y)->(0,0)`
So it is symmetrical about the y-axis. This happens because no matter what value you use for `x` the consequential value of `y` is always positive.

Consider what happens next. Take every value of y and add 4 to it.

The consequence of this is that the general shape graph of V is lifted upwards by 4 graph{y=abs(x)+4 [-6, 6, -3, 10]}
