Given:
.
f%28x%29+=+abs%28x-3%29+-+4
.
Just pick some convenient values of x and solve for f(that value). For example let's set
x at 0. The equation becomes:
.
f%280%29+=+abs%280-3%29+-+4+=+abs%28-3%29+-+4+=+%2B3+-4+=+-1
.
If you need this in the form of an (x,y) point, then this answer is (0,-1).
.
Let's do it again. Set x = -5 to get:
.
f%28-5%29+=+abs%28-5-3%29+-+4+=+abs%28-8%29+-+4+=+%2B8+-4+=+%2B4
.
and in the form of an (x,y) point, this answer is (-5,+4).
.
And finally a 3rd point. Set x = +6 and the equation becomes:
.
f%286%29+=+abs%286-3%29+-+4+=+abs%283%29+-+4+=+%2B3+-4+=+-1
.
and in point form this is (6,-1).
.
You can try other values, but hopefully this will give you the idea of finding points on
the graph of f(x) by just assuming values of x and calculating corresponding values for
f(x) or y.
