Select the correct answer. graph A Graph shows a piecewise function plotted on a coordinate plane with credit on X-axis and minimum amount due on Y-axis. Four segments are represented with a closed endpoint and an open endpoint. graph B Graph of piecewise function with credit on X-axis, minimum amount due on Y-axis. Three segments with closed and open endpoints, and segment four with two closed end points are shown. First at (100, 00), (500, 100). Second at (500, 300), (1000, 300). graph C Graph shows a piecewise function plotted on a coordinate plane with credit on X-axis and minimum amount due on Y-axis. Three segments are represented with a closed endpoint and an open endpoint. graph D Graph shows a piecewise function plotted on a coordinate plane with credit on X-axis and minimum amount due on Y-axis. Three segments are represented with a closed endpoint and an open endpoint. A credit card company uses these rules to calculate the minimum amount owed: For a bill of less than $100, the entire amount is due. For a bill of at least $100 but less than $500, the minimum due is $100. For a bill of at least $500 but less than $1,000, the minimum due is $300. For a bill of $1,000 or more, the minimum due is $500. Which graph shows the minimum amount due for a credit amount of x (given that the credit limit is $2,000). A. graph A B. graph B C. graph C D. graph D
