A function represents the amount of air remaining in an exercise ball that originally had 4,500 cubic inches of air and is losing 6% of its air every minute. Determine if this situation represents a linear model, quadratic or exponential model and write the function for this model.
O A It is a system of equations, y = 6x y = 4500x
OB. It is quadratic, f(x) = 6x²+ 4500
OC. It is exponential, f(x) = 4500(0.94)*
O D. It is linear, f(x) = -6x + 400
