On graph paper, graph the parabola $y = 2x^2 - x - 15$.

1. What are the $x$-intercepts of the parabola? Write your points in $(x, y)$ form.

   Hint (a):

   Set $y = 0$ and factor, or use the quadratic formula to solve for the $x$-intercepts.

2. How is the graph of $y = -(2x^2 - x - 15)$ the same or different? Can you tell without graphing?

   Hint (b):

   How does the negative sign affect the slope? The $y$-intercept?

   More Help (b):

   Would the $x$-intercepts change?
