Find an expression for the function whose graph is the bottom half of the parabola x + (y - 8)2 = 0.

X + (y - 8)^2 = 0
(y - 8)^2 = -x
y - 8 = √-x
y = √-x + 8

Required equation is y = √-x + 8        x ≤ 0

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
