A model has values -3, -6, -12, and -24 for x=0,1,2,3. Which statement is correct?
A
The values are quadratic because their absolute values double.
B
The values have a constant difference of -3, so they are linear.
C
A constant ratio of 2 gives an exponential model that decreases toward negative infinity.
D
The values are not exponential because exponential outputs can never be negative.
