13. Let f(x) = 4x' - 24x + 11. (a) Write f(x) in standard form. (b) Give the vertex and axis of symmetry of the graph of f(x). (c) What is the range of the function f(x). 14. Use the following function to solve the problems below. f(x) = x - 25 32-4 -9 5>2. (a) Find f(3). (b) Find the y-intercept. (c) Find the -intercept(s).15. The graph of y = -|x - 4) is obtained from the graph of y = (x| after (a) A shift left and then a reflection about the x-axis (b) A shift right and then a reflection about the x-axis (c) A shift left and then a reflection about the y-axis (d) A shift down and then a reflection about the x-axis (e) None of these 16. In the triangle below, or = 35' and b = 6. C h (a) Find B (b) Find a. (Give the best answer you can without the use of a calculator.)
