Solve by graphing: y=3(x-2)^2-3

ANSWERS BELOW

Step 1: Identify a, h, and k.
a=3, h=2, k=-3

Step 2: Plot the vertex at (2,-3).

Step 3: The axis of symmetry is the line
x = 2

Step 4: Evaluate the function at two other x-values:
When x = 1, y = 0
When x = 0, y = 9

Step 5: Plot the points (1, 0) and (0, 9)

Step 6: use the property of symmetry to plot to more corresponding points on the right side of the vertical line.
{Plot (3, 0) and (4, 9)}

Step 7: Identify the zeros of the graph.
The roots of the equation are 1 and 3.
