A hospital purchases a new magnetic resonance imaging (MRI)machine for $600,000.The depreciated value y (reduced value)after t years is given by y = 600,000 - 20,000t,0 ≤ t ≤ 6.Sketch the graph of the equation.

The equation y = 600,000 - 20,000t represents a linear function with a negative slope (-20,000). The y-intercept is 600,000, which represents the initial value of the MRI machine when it was purchased. The domain is limited to values between 0 and 6 years because it is unlikely that the machine will be used beyond that time frame. Thus, the best choice is C, which correctly represents a linear function with a negative slope and a y-intercept of 600,000 over a domain of 0 to 6 years.
