Which equation matches the quadratic equation displayed in the graph?

a) y = x2 - 1
b) y = x2 + 1
c) y = (x + 1)2
d) y = (x - 1)2

Step-by-step explanation:

vertex: (m,n) = (0,1)

f(x) = a(x-m)² + n = a(x-0)²+1

y = x² +1

Tip: you could pick any point on the curve and plug the x value in the given equations to see  if you get the y value

eg. if you pick (x,y) = (-2,5) as your point, the right equation would give you 0 which is y.

x²+ 1 =y; -2²+1 = 4+1=5; so when x is -2, y is 5
