- How do the graphs of the functions f(x)=x2 and f(x)=x21 differ? We graphed them at the start of this section. What is the difference between their graphs? How are their graphs the same?arrow_forwardThe graph of fx=1/x is a .arrow_forwardIf the point (3,4) is on the graph of the function f , then the point ( __ , __ ) Is on the graph of f1 .arrow_forward
- Suppose you have a job that pays $8.50 per hour and you work anywhere from 10 to 40 hours per week. a. Write an equation, with a restriction on the variable x, that gives the amount of money, y, you will earn for working x hours in one week. b. Use the function rule you have written in part (a) to complete Table 4. c. Construct a line graph from the information in Table 4. d. State the domain and range of this function.arrow_forwardA company determines that its weekly profit from manufacturing and selling x units of a certain item is given by Px=-x3+3x2+2880x-500. Use a graphing utility to find the weekly production rate that will maximize the profit.arrow_forwardWhat is the difference between the input and the output of a function?arrow_forward
