Can you please help me finding the vertex and intercepts for this equation, and whether it opens up or down?
y + -3x squared + 6x
I suppose the question is:
y= -3x^2 + 6x
In that case we have to factor -3 and complete the square:
-3x^2 + 6x= -3( x^2 - 2x)= -3(x^2 - 2x + 1 -1 )= -3( (x-1)^2 - 1)= ...
Vertex and intercepts are found. The solution is detailed and well presented. The response received a rating of "5" from the student who originally posted the question.
