Hello! If you put the graph into a calculator like Desmos, it’ll practically give you the answers!
The x-intercepts/“zeros” should be (-2,0) and (4,0). (They’re where the graph goes through the x-axis)
The y-intercept is (0,-8). (Of course the y-axis)
The vertex is the bottom point of the graph where it has the little curve. It should be (1,-9).
Last but not least, the axis of symmetry should be 1 (Which is the where the graph could fold perfectly. It’ll always be located on the x-axis.)
