Math Problem Statement

Determine whether the a-value is positive or negative. Provide an appropriate reason. (1 point) Responses The a-value is negative because the graph is of a parabola that opens down. The a -value is negative because the graph is of a parabola that opens down. The a-value is negative because the x-intercepts are negative. The a -value is negative because the x -intercepts are negative. The a-value is positive because the graph is of a parabola that opens up. The a -value is positive because the graph is of a parabola that opens up. The a-value is negative because the y-intercept is negative.

Solution

To determine whether the a-value is positive or negative, we need to examine the shape and orientation of the parabola.
