 * How many x-intercepts are there?
 * ======‍‍‍ What is the x-value(s) when f(x)= 2? ======
 * ======‍‍‍ What is the x-value(s) when f(x)= -1 ======
 * ======‍‍‍ If you were to shift the whole graph to the left, how many x-intercepts would there be? ======
 * ======‍‍‍ If you were to shift the original graph down lower so that the bottom point is at f(x)= -10, how many x-intercepts would there be? ======
 * ======‍‍‍ Describe how you would need to shift the original graph so there are NO x-intercepts. ======

=
‍‍‍ If you shift the graph to the left it would still have two x-intercepts. ======

=
‍‍‍ If the lowest point was f(x)=-10, there would be no x intercepts. ======

=
‍‍‍ In order to have 0 x-intercepts you would have to shift the graph up so the vertex is no longer on the axis. ======

__** 4.3 **__ When solving absolute value equations, you have to basically solve to get rid of the absolute value. Once the absolute value sign is gone, you break the inequality into two separate inequalities, one with a positive answer, and one with a negative.
