The scenario represents a linear function. The rate is at a constant increase therefore it is linear.
Linear because it’s a constant rate
Since it’s doubled, and doesn’t go at a constant rate, it is a exponential function
Exponential since it increases by a multiplicative rate. It’s not constant
It’s number 12!!!!! I know it already got answered
The rate of change is meaning the slope. The slope of A is 8, therefore, the answer would be 7.
hope this helps :)
