Question

The vertex is considered the turning point of a parabola. Take a second and think about what that means in terms of average rate of change. Look at the graph above. Calculate the slope between each of its five points. Check your work. Working from left to right, the slope works out like this: (3, 0) to (4, 6) (4, 6) to (5, 8) (5, 8) to (6, 6) (6, 6) to (7, 0) m = the quantity of y sub 2 minus y sub 1 over the quantity of x sub 2 minus x sub 1 m = the quantity of y sub 2 minus y sub 1 over the quantity of x sub 2 minus x sub 1 m = the quantity of y sub 2 minus y sub 1 over the quantity
