Use the parabola tool to graph the quadratic function f(x)=(x−2)(x−6) graph the parabola by first plotting its vertex and then plotting a second point on the parabola.

What parabola tool?

Step-by-step explanation:

I went ahead and graphed the quadratic function however, you should learn how to graph it yourself the way they are asking you to using the "parabola tool", because I cant really show you my steps in graphing it since I don't know what your parabola tool is.

Sorry

the answer should be D

Step-by-step explanation: you need to substitute the x and Y variables with the coordinates. The left side of the coordinates is variable X and the right is verifiable Y so you  substitute those for x and y.

Ex: X + 2y=8 and you have coordinated (8,0)

You substitute those in: 8 + 2(0)=8

2 times 0 is zero leaving you with 8=8.

You continue to do that with the other coordinates leading you to the conclusion that the correct answer is D.

Hope it helps.
