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

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]}
