- The circumference C of a circle is a function of its radius given by C(r)=2r. Express the radius of a circle as a function of its circumference. Call this function r(C) , Find r(36) and interpret its meaning,arrow_forwardUse the Vertical Line Test to determine whether the graph represents y as a function of x.arrow_forwardUse your schools library, the Internet, or some other reference source to find real-life applications of approximations of functions.arrow_forward
- 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 f(x)=10x is reflected about the x-axisand shifted upward 7 units. What is the equation ofthe new function, g(x) ? State its y-intercept, domain,and range.arrow_forwardSuppose 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_forward
- Functions in Words Express the function (or rule) in words. f(x)=2x+3arrow_forwardWhat is the composition of two functions, fg ?arrow_forwardTo graph the function f, we plot the points (x,) in a coordinate plane. To graph f(x)=x22, we plot the points (x,). So the point (3,) is on the graph of f. The height of the graph of f above the x-axis when x=3 is _______. Complete the table, and sketch a graph of f. x f(x) (x,y) 2 1 0 1 2arrow_forward
