3- Let consider the function y=x-Ix-1l-Ix-2l write this functionas a piecewise function and then graph it.

In​ 2000,53 % of the residents in a large city regularly used newspapers for getting news and this has decreased at an average rate of approximately 1.1 % per year since then. Find a linear function in​ slope-intercept form that models this description. The function should model the percentage of​ residents,Upper P left parenthesis x right parenthesis comma who regularly used the news outlet x years after 2000.

Two input/output tables are shown below.   (a) Table A is not a function. Change the table so that it is a function.  Why was Table A not a function?   (b) Table B is not a function. Complete the table with values to show it is not a function.

Use the vertical line test to see if the graph has a function

Use the graph of the function to find its domain and range. Write the domain and range in interval notation.

Consider the set of all ordered pairs where the first coordinate is a person’s name and the second coordinate is the name of the person’s uncle. Thus, the ordered pairs in the set look like (person, person’s uncle). Is this relationship a function? Explain how you know.

The cost of renting a canoe is $20 for the first 4 hours and $4 per hour for additional hours. Write a piecewise function that represents the cost of renting a canoe for 0 to 8 hours.
