1. Refer to the graph given in Section 4.1 Exercise 28 of the text. This graph represents a quadratic function of the form f(x) = a(x - 1) (x - 12). (a) Determine the values of r1 and r2 (b) Write the function in the form f(x) = ax~ + bx + c O a. (a) -3 and 1 (b) f (x) = -2x2 - 4x + 6 b. (a) 3 and -1 ( b ) f (x ) = 2x + 4x - 6 OD c. (a) -3 and 1 (b) f(x) = 2x + 4x - 6 O d. (a) 3 and - 1 (b ) f (x) = -2x - 4x+6 Topic covered in current section | Report a
