Math Is Connections: A, B, C, D Project A cubic polynomial has four coefficients, A, B, C, D. S (x ) = Ax3 + BX? + CX + D Use your set of four integers from task 74 as A, B, C, D Task 1: Solve the equation Ax + Bx'+ Cx + D=0. Discuss the roots (the solutions) from task 1. How many are real numbers? How many of the real roots are rational number roots? How many are complex numbers that are not real? Task 2: Graph the polynomial S(x) = Ax + Bx2 + Cx +D. Label the intercepts. Show the scale. Task 3: Let F(x) =LN(x) and find the composition Fo S. Task 4: Identify the domain of FoS. Ax + B Task 5: Graph the rational function R(x) = CX + D Task 6: Identify R-1
