Question 592032
The vertex of the parabola below is at the point (4, 6.5)
and the point (5, 4.5) is on the parabola.
What is the equation of the parabola?
**
Standard form of equation for a parabola: y=A(x-h)^2+k, (h,k)=(x,y) coordinates of the vertex.
y=A(x-4)^2+6.5
Solving for A using coordinates of given point (5,4.5)
4.5=A(5-4)+6.5
4.5=A(1)+6.5
A=-2
Equation: y=-2(x-4)^2+6.5
answers are c and d which are duplicates.
