Your answer should be in the form (x-coordinate, y-coordinate).

(Hint: Find the x-coordinate by using the Midpoint Formula [-b / (2a)]. Then find the y-coordinate by plugging the x-coordinate value into the original equation and solving for “y.”)

How do I even begin???

I will help with this but for the other two just look at them

What happens for huge negative x?

What happens for huge positive x?

for this one follow directions

-b/2a = -20/-4 = 5

that means that the graph of this parabola crosses the x axis equal distance left and right of x = 5

so your axis of symmetry is x = 5

Now for the y value of the vertex, just solve using x = 5

y =-2(5)^2 + 20*5 + 1
