Y=X2+bx+c (the 2 means squared)
Y = 16 when x= 0
Y= 0 when x=-2
Find the values of b & c
set up two equations and solve
the 1st one is a gift ... 16 = 0^2 + (b * 0) + c ... 16 = c
0 = (-2)^2 + (-2 b) + 16
Y = 16 when x= 0
Y= 0 when x=-2
Find the values of b & c
the 1st one is a gift ... 16 = 0^2 + (b * 0) + c ... 16 = c
0 = (-2)^2 + (-2 b) + 16
