Question: Make the given changes in the indicated examples of this section and then solve the resulting problems.

In Example, change the - sign before 8x to + and then sketch the graph.

Example: Graphing a parabola-vertex-y-intercept

For the graph of the function y = 2x2 - 8x + 6, find the vertex and -intercept and sketch the graph. First, a = 2 and b = -8 This means that the x-coordinate of the vertex is

-b = -(-8) = 8 = 2
2a    2(2)     4

and the y-coordinate is

y = 2(22) - 8(2) + 6 = -2
