What are the x-intercepts of the parabola? y = ¼(x + 2)(x - 6) List the x-intercept(s) in the form x={lowest, highest}

In factored form you can see the ______ of the graph easily.

• y-intercept
• vertex
• x-intercept(s)

For the following graph, list the x-intercept(s) in the form x={lowest, highest}. If there is no x-intercept, write "no solution" (all lowercase).

For the following graph, list the x-intercept(s) in the form x={lowest, highest}. If there is no x-intercept, write "no solution" (all lowercase).
