The inches of rainfall on mount waiale on Kauai in Hawaii is represented by the function f(x)=3^x+1-22 scientist are useing equations to study rain fall from year to year​. Calculate how much rainfall there was in year four and In year nine. You must show all of your work and calculate.

Step-by-step explanation:

we are given a function

where x represents the years f(x) represents the amount of rainfall

so to figure out the amount of rainfall in year 4 we can substitute 4 for x

simplify addition:

simplify square:

simplify substraction:

likewise In the year 9

simplify addition:

simplify square:

simplify Substraction:

hence,

there was 221 and 59027 in year four and In year nine

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
