Suppose a parabola has vertex (5, –3) and also passes through the point (6, 1). Write the equation of the parabola in vertex form.
A. y = (x – 5)2 – 3
B. y = 4(x – 5)2 – 3
C. y = 4(x + 5)2 – 3
D. y = 4(x – 5)2 + 3

Best ResponseYou've already chosen the best response.0just kidding i thought it was 5. so it has to be c since thats the only one with +5

Best ResponseYou've already chosen the best response.2You're perfectly right. Now check if (6,1) is also a point in both the choices.

Best ResponseYou've already chosen the best response.0a and b both have 5 its +5

Best ResponseYou've already chosen the best response.2The standard form is this:\[\rm y = a(x  h)^2 + k\](h,k) is the vertex.

Best ResponseYou've already chosen the best response.0yeah i get it now. but how do i check if (6,1) is also a point?

Best ResponseYou've already chosen the best response.2You plug in 6 for x and 1 for y, then check if both sides are equal.
