Answer: Choice B) The graph opens down

The negative 'a' value means the parabola opens downward. One way to remember it is that the positive 'a' value means "happy face" or "smile", and a negative 'a' value means "frowny face".

See the image attachment and note the color coding of the graphs.

NemiM [27]

Answer:

y = 20000(0.875)^11

y = 460.38

So, the car's value after 11 years will be $460.38
