Question

Find the quadratic function .

Y = ax^2 + c with a graph that includes (0, 1/2) and (-3, 73/2)


A. y = 4x^2 - 1/2
B. y = 4x^2 + 1/2
C. y = -4x^2 - 1/2
D. None of these

Answer 1

put x=0 in y you have 1/2 c gain from that
then put x=-3 in y you have relation between c,a then solve it for a
