The inputs of the function are , the number of bedrooms, and y, the square footage, of homes in Castle Rock, Colorado. The output is the sale price of the home. Which of the following would be the correct function value for a 6-bedroom home with 2,290 square feet that is for sale for $370,000? O f (2290) = 6 (370000) O f (2290, 6) = 370000 O f (6, 370000) = 2290 O f (370000) = 6 (2290) O f (6, 2290) = 370000Which chart or graph would be best choice for determining if a relationship exists between the number of students attending school in a semester and the total amount of money spent by students on textbooks during that semester? O Time Series Plot O Bar Chart O Scatter Plot O Pie Chart O Any of the above charts or graphs would work for this data.Tucker used the Quantitative Reasoning Process to create a plan to pay off his auto loan of $6,285.
