The general expression for the exponential function is

Note that the graph of each exponential function passes through the point (0,a), because

First point in options B and D is (0,1), then

and you get the expression

Points (0,1), (1,3), (2,9) and (3,27) represent the powers of 3. In this case

Points (0,1), (1,2), (2,5) and (3,10) couldn't generate any exponential function, because if

Answer: correct choice is D

1) In what way is the point unusual? Does it have high leverage, a large residual, or both?

2) Do you think that point is an influential point?

3) If that point were removed, would the correlation be- come stronger or weaker? Explain.

4) If that point were removed, would the slope of the re- gression line increase or decrease? Explain
