13. R(x) = (2x+6)(x-1) (4-x) (x+2) Without using technology to create a table or graph, find any vertical asymptote(s) and any horizontal asymptote(s) 14. For the function f(x) = 10 - 5x find the average rate of change from x = a to x = a + h 15. Use the following table to answer the question below: C 3 4 6 9 13 D 2 4 4 6 6 F 4 8 16 32 64 (a) Is D a function of C? Remember to clearly explain your answer (b) For this question use C for the inputs and D for the outputs. Is the data linear? Remember to show your work so that it is clear how you arrived at your answer 16. Extra Credit (5 points each): (a) A function is labeled as, "even" if has the property that: f (-x) = f(x) for all values of x. Use this definition to show convincingly whether or not the function f(x) = x2 + 2* + 2 is "even". (b) Solve 3 . 2* = 2x + 5 by using your technology's graphing feature Remember when you use technology to help solve a problem, your work should reproduce the relevant parts of any tables or graphs used
