Question

The vertex of the graph of a quadratic function is (3, 1) and the y-intercept is (0, 10). Which of the following is the equation of the function?

Answer 1

The choices are:

A.y=2x^2-12x+10

B. y=-1/2x^2+3x-11/2

C. y=x^2-6x+10

D. 2x^2-7x+4

Answer 2

y = a(x-3)^2 + 1
10 = a(0-3)^2+1, so a = 1

Looks like (C) to me
