Question

Please show the work. Any help is appreciated, thanks!!

monthly membership fee of only $2.25, Biffs Bananas will deliver quality fresh bananas to your doorstep every morning! The per-banana charge is a dime for the first 20 bananas delivered, and a nickel for any additional bananas. There's also a penny-per-banana fuel surcharge on all #7. For a orders, Sketch a graph of the cost function for x bananas delivered in a month, then determine its formula in piecewise form #8. Consider the degree-two polynomial function f(x) = 2x2 x - 6 a) Solve for the y-intercept b) Solve for the x-intercept(s). c) Where is the line of symmetry? d) What are the exact coordinates of its vertex? e) Using the above info, sketch its graph # 9. Sketch a nice graph of f(x) 4x x3, then answer the following questions: a) What are the coordinates of its intercepts? b) Over what interval(s) is the function decreasing? (Use interval notation) #10. Graph a function (just one function) that has all the following properties: a) Local or relative minimum of 3 at 4 b) Global or absolute maximum of 5 at 8 c) Domain [1, 10) X 3 #11-12. Follow these steps to sketch a graph of f(x) 2 x6x8 [4 pts] Determine the location(s) of any vertical asymptote(s). 4 pts] Determine the location of any horizontal asymptote. [2 pts] Solve for any x-intercepts [2 pts] Solve for any y-intercept. as needed, to finish the graph [4 pts] Plug in a few more points,
