A parabola has a vertex of (3, –2) and a y-intercept of 7. What is the equation of this parabola? 1) y = 2(x - 2)^2 - 1
2) y = (x - 3)^2 - 2
3) y = (x + 1)^2 + 7
4) y = (x + 3)^2 - 1

2) y = (x - 3)^2 - 2

Step-by-step explanation:

y = -2

x = 3

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
