Graph y = x2

Step 1: Make a Table Step 2: Plot the points Step 3: Connect the points to create a parabola

Quadratic Functions Y = x2

Vertex: Highest or lowest point of parabola

Axis of Symmetry: Line that passes through the

vertex Cuts parabola symmetrically

Step 1: Make a Table Step 2: Plot the points Step 3: Connect the points to create a parabola

Graph y = 2x2 Graph y = (1/2)x2

Step 1: Make a Table Step 2: Plot the points Step 3: Connect the points to create a parabola

Graph y = -2x2

Graph y = -(1/2)x2

Graph y = x2 + 5

Graph y = x2 + 5

Graph y = x2 - 5
