Using the quadratic equation: a=1 b=-1 and c=0
Find the horizontal and vertical coordinate of the vertex:
h=-b/2a
=-(-1)/2(1)
=1/2 (horizontal)
k=f(h)
=f(1/2)
=(1/2)^2-1(1/2)
=-1/4 (vertical)
Vertex - (1/2,-1/4)
when these are plugged in to the quadratic equation:
f(x) = (x-1/2)^2-1/4
Ungraded Grade: 0/3.0
Total grade: 1.0×2/6 + 1.0×1/6 + 0.0×3/6 = 33% + 17% + 0%
Feedback:
