An Investment of $12,000 is losing value at a rate of 4% each year. Write an exponential function to model the situation, then find the value of the Investment after 9 years.

After 9 years:

7,680

Step-by-step explanation:

4%=0.04

1 year = 12,000 x 0.04=480

9 years= 480 x 9 = 4320

12,000-4320= 7,680

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.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
