Question

Need some help, please. What do I plot? I attempted to figure the questions out many times, but I've come to no clear conclusion, whoops.

Answer 1

vertex is (4,-4) and another point is (6,0) or you could use (2,0) or many other options :)

Explanation:

The cool thing about this question your quadratic is in factored form so your x-intercepts are easy to figure out, they are 2 and 6.

So you can plot (6,0) and (2,0).

The vertex will lie half between x=2 and x=6... so it lays at (6+2)/2=4

We just have to find the y-coordinate for when x=4.

Plug in 4 gives you (4-2)(4-6)=(2)(-2)=-4.

So the vertex is at (4,-4).
