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.
I know that the second one the fourth one and the fifth one are arithmetic but I’m not sure about the others I think there are only three but don’t count me on it
