Answer:
The answer is B
Step-by-step explanation:
Answers talk about rate of change meaning slope.
For function 1 we choose two points, they specify [1,2].
Use the slope formula for points (1,-3) & (2,3) = 6
For function 2, the equation is shown in y-intercept, basically the slope is (1/4)^x and if you replace x with [1,2] you get really low values.
For function 3 is easy since you can count the units with rise/run giving and slope of 2 or 2/1. (2 and 2/1 is the same thing)
