Question

What is the vertex of the graph of y=1/4(x-2)^2+6

Answer 1

Vertex form of a parabola:

\[y = a(x-h)^2 + k\]the vertex is at \((h,k)\)

be careful of the signs...

Answer 2

as a learning reinforcement exercise, plug in the values \(x = 1, x = 2, x = 3\) and look at the values of \(y\) produced.
