Which of the following describes the growth rate of the exponential function in the graph below? a.)for each x increase of 1, the y increases by a common difference of 3. b.)for each x increase of 1, the y increases by a common factor of 3. c.)for each x increase of 1, the y increases by 4 more than the previous increase. d.)for each x increase of 1, the y increases by doubling and then adding 1.will give brianliest 

Any exponential function is of the form y= .Here a is any value greater than 0.

In the given graph As x increases,y heads to infinity.As x decreases, y tends to 0 . The points given in the graph has x increasing by 1 unit and y is increasing by a multiple of 3.The 3 represent the a value of the function which is also the scale factor.

Among all the given values option B.)For each x increase of 1, the y increases by a common factor of 3 is the right answer.

Option B.
