Which is the graph of a quadratic equation that has a positive discriminant?
Answer
A
Image with description A coordinate plane displays the x-axis labeled from negative 5 to 5 in increments of 1 and the y-axis labeled from negative 5 to 5 in increments of 1. An upward-opening parabola has a vertex at the point negative 1 comma 0. It passes through approximately the points negative 2 comma 1 and 0 comma 1, then continues upward through approximately negative 3 comma 4 and 1 comma 4.
B
Image with description A coordinate plane displays the x-axis labeled from negative 5 to 5 in increments of 1 and the y-axis labeled from negative 5 to 5 in increments of 1. An upward-opening parabola has a vertex at the point 0 comma negative 1. It passes through approximately the points negative 1 comma 0 and 1 comma 0, then continues upward through approximately negative 2 comma 3 and 2 comma 3.
C
