3. The point (2, 1) is found on the function f(x) = x2. If f(x) = x2 undergoes a reflection about the x-axis, is vertically stretched by a factor of 3, and is translated 8 units right and 4 units down, the new point is (a, b). The values of a and b are and 6. What is the range of the graph of the quadratic function f(x) = (x - a) -b? A. [-b, -0) C. (60, -b] B. [-b, 20) D. (-00, -b] Use the following information to answer the next question. A math teacher asks her class to solve the quadratic equation 6x - 13x = 5. Two students, Rhett and Vidor, hand in the work for their solutions. Rhett: Vidor: 6x - 13x= 5 6X - 13x= 5 6x - 13x - 5=0 6x - 13x - 5=0 6x - 10x- 3x - 5=0 x= 13+ V(-13)2-4(6)(-5) 2x(3x - 5) - 1(3x - 5) = 0 2(6) (3x - 5)(2x - 1) = 0 = 13v169 -120 12 = 13v49 12 7. Based on the work shown for each student, which of the following statements is true? A. Rhett's work and Vidor's work will both lead to correct solutions. B. Rhett's work and Vidor's work will both lead to incorrect solutions. C. Rhett's work will lead to a correct solution, and Vidor's work will lead to an incorrect solution. D. Rhett's work will lead to an incorrect solution, and Vidor's work will lead to a correct solution
