Question 411687: 1. Identify the vertex of each parabolas, and idenitify if it is a maximum or minimum.
a. f(x)= x^2 - 2x + 6
b. f(x) = 4(x-3)^2-1

a) minimum
vertex = (1,5)
b) minimum
Vertex = (3,0)
If the x^2 part is positive, it opens up, so the vertex is at the minimum.
If the -x^2 part is negative, it opens down, so the vertex is at the maximum.
These are both positive, so they open up.
