Question
1. What is the vertex of each of these parabolas?
a. y = (x –7)2 +4 b. y = 3(x + 7)2 – 4
a. y = (x –7)2 +4 b. y = 3(x + 7)2 – 4

x greater than 1

to type an exponent, we use the ^
a) y = (x-7)^2 + 4
vertex is (7,4)
you must learn the pattern to pick out the vertex from that standard form
if y = a(x-p)^2 + q, the vertex is (p,q)
(notice the x value is opposite of p, the y value is the same as q )
