Question

Every square meter of solar paneling produces 0.2 kilowatts of electricity. Which of the following models this situation?

Answer 1

Question choices:

linear function with a negative rate of changelinear function with a positive rate of changeexponential decay functionexponential growth function

Answer 2

Somebody else posted this exact same question just yesterday.
HE didn't include the list of choices either.

Here are a couple of equations that model the situation:

Power = 0.2 (length of side of a square solar panel)²
or
Power = 0.2 (length of the solar panel) (width of the solar panel) .
