Guided Practice

In each of the equations, the vertex rises or drops along the y-axis. The value of y changes, but the value of x does not change. The x-value remains zero.

Look at the graph of y = 2x^2 + 1 and find the y-value of the vertex.


Which point is the vertex of y = 2x^2 + 1?


A.
(0, 0)


B.
(0, 1)


C.
(1, 0)


D.
(1, 1)
