Find the coordinates of the midpoint for the following equation: y = 2x^2 + 20x + 1.
Your answer should be in the form (xcoordinate, ycoordinate).
(Hint: Find the xcoordinate by using the Midpoint Formula [b / (2a)]. Then find the ycoordinate by plugging the xcoordinate value into the original equation and solving for “y.”)
How do I even begin???

ALGEBRA 
Damon,
y = 2x^2 + 20x + 1
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
