1. Given the parabola y = -9x2 + 18x-11, list the direction that the parabola opens, the vertex, the y-intercept, and the number of real roots.
List the answers in the order requested, separated by commas.
-Direction: enter up, down, left, or right.
-Vertex: enter as a coordinate pair where any non-integer coordinate is entered as a fraction in simplest form.
-Y-intercept: Enter only the y-coordinate.
-Number of real roots: enter a number.
For example, if the parabola opens to the right, the vertex is at (1, 5), the y-intercept is 4, and there are 2 real roots, then the answers should be entered as "right, (1, 5), 4, 2”
