Given the list of ordered pairs, identify the y-intercept.
(1, 3),  (9,10),  (0, -4),  (8, 9),  (4, 0)

• (1,3)

• (0,-4) and (4,0)

• (0,-4)

• 3, 10, -4, 9, 0

What is the x-intercept shown on the graph?

• (2, 0)

• (-2, 0)

• (0, 3)

• (3, 0)

• The graph has a y-intercept at (2, 0).

• The coordinates of the vertex are (1, 1).

• The graph of the function opens downward.

• The x-intercepts are at (0, 0) and (2, 0).

• The y-intercept of the graph is at (0, c).

• The graph has an x-intercept at (c, 0).

• When a < 0 the graph opens downward.

• The graph has two x-intercepts.

• If b = 0, then the vertex is on the y-axis.
