Question 939735
Write the quadratic function in the form
f(x)=+a(x-h)^2+k (vertex form of equation for a parabola)
Then, give the vertex of its graph.
f(x)=−2x^2+12x-20
***
−2x^2+12x-20
complete the square:
f(x)=-2(x^2-6x+9)-20+18
f(x)=-2(x-3)^2-2
This is an equation of a parabola that opens down with vertex at (3,-2)
