Question

Which of the attached graphs represents pure exponential growth?

Answer 1

We can immediately eliminate B & C.

B is showing decay and C is growing but rate of growth slows down after a while to negligible amount.

Both A and D are showing growth but we want PURE EXPONENTIAL GROWTH.

A is growing exponentially but after a certain while, whereas D is exponentially growing from the start. This is pure exponential growth. So our answer is the graph of D.

ANSWER: The graph in D is showing pure exponential growth.

Answer 2

The answer is D bc it is continuously increasing
