Which graph is a parabola? On a coordinate plane, a curved line opens up and left in quadrants 1 and 2. It is asymptotic to the negative x axis and crosses the x-axis at (negative 4, 0) and crosses the y-axis at (0, 1). On a coordinate plane, a curved line opens up and down in quadrants 1 and 3. It crosses the x-axis at (negative 1, 0), turns to the right, crosses the y-axis at (0, 1), then turns up sharply. On a coordinate plane, a parabola opens up. It goes through (negative 2.2, 10), has a vertex of (0.25, negative 1), and goes through (2.6, 10). On a coordinate plane, a curved line opens up and left in quadrants 1 and 2. It goes through (negative 3.3, 10), crosses the y-axis at (0, 1), and is asymptotic to the positive x-axis.
