This exercise requires us to connect two main pieces of information about quadratics.

1. The solutions, or zeros, on a graph are where the curve crosses the $x\text{-}$axis.
2. The value of the discriminant tells us the number of the solutions.
First, let's identify the number of solutions for each graph.
$\text{Graph A}$

$\text{Graph B}$

$\text{Graph C}$

Now, let's connect the number of solutions to our graphs..

Graph Number of solutions
Graph A One Solution
Graph B Zero Solutions
Graph C Two Solutions
