Find the vertex of the functions given below.
1. y=(x4)(x+2)
2. y=2x^24x+1
The midpoint of the xintercepts of a parabola has the same x value as the vertex.
the xintercepts are obviously x=4 and x=2
so the x value of the vertex is......
sub that back into the equation to get the y value.
for the second one, just use the method of completing the square.
