What is the vertex of #y= 3(2x-1)^2-12 #?
This is a parabola in vertex form.
Vertex form is a useful way of writing the equation of a parabola so that the vertex is visible within the equation, and doesn't require any work to determine.
Vertex form is:
From this, we can see that
The only tricky thing to watch out for is that the sign of the
