Question

Which equation has a graph that is a parabola with a vertex at (5, 3)?

A; y = (x – 5)2 + 3
B; y = (x + 5)2 + 3
C; y = (x – 3)2 + 5
D; y = (x + 3)2 + 5
the answer is D i think

Answer 1

Its A because when you do (x-5)=0 you add 5 to get x=5 and thats your x value and the 3 for your k is your y value
