The ordered pairs model an exponential growth function. {(−1,21.875), (0,35), (1,56), (2,89 .6)} what is the function equation? enter your answer in the box.

Step-by-step explanation:

Find the exponential function in a form

1. At x=0,

2. At x=1,

Therefore, the expression for the exponential function is

Note that

and

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
