Step 1 : Set up  a table of values

Plug in different values of x in y = x^{2} -2x -8

x          y

-------------

0        -8

4         0

-2        0

Step 2: Plot these points on the graph, join them to get a parabola




Step 3: Name the y-intercept and the x-intercept

Remember what is the y-intercept

The y-intercepts is (0,-8). The x-intercepts are (-2,0) and (4,0)

Step 3: Name the vertex or the lowest point

The vertex is (1,-9)
