(a)
The independent and dependent variables.
(a)

Answer to Problem 59SR
The independent variable in the given data is the number of sides as it is not dependent on the interior angle sum.
The dependent variable here is the interior angle sum as it is dependent on the number of sides.
Explanation of Solution
Given:
Calculation:
The independent variable in the given data is the number of sides as it is not dependent on the interior angle sum.
The dependent variable here is the interior angle sum as it is dependent on the number of sides.
(b)
The domain and range of given data.
(b)

Answer to Problem 59SR
Domain is all the integers greater than or equal to 3.
Range is all positive integers that are the multiple of 180.
Explanation of Solution
Given:
Calculation:
Domain is represented by the input values of the function. Here, the input value is the number of sides of the
Range is identified as the output values of the function. Here, the output value is the interior angle sum of the polygon i.e. 180 to 900, each being the multiple of 180.
Domain is all the integers greater than or equal to 3.
Range is all positive integers that are the multiple of 180.
(c)
Whether the given function is discrete or continuous.
(c)

Answer to Problem 59SR
The given function is discrete as the number of sides has to be a whole number.
Explanation of Solution
Given:
Calculation:
The given function is discrete as the number of sides has to be a whole number.
