Step-by-step explanation:

A quadratic is a parabola, either shaped like a cup (positive parabola) or a mountain (negative parabola).  A linear expression is a line.  If the line intersects the parabola it can possibly go through both of the branches of the parabola--the one to the right of the vertex and the one to the left of the vertex.  It can go through one branch only, depending upon the steepness of the line, or it can completely miss it and not go through at all.  But the max number of intersections is 2.

C. Two

Step-by-step explanation:

Mark is solving an equation where one side is a quadratic expression and the other side is a linear expression. He sets the expressions equal to y and graphs the equations. What is the greatest possible number of intersections for these graphs?

none

one

two

infinitely many
