Evaluate logarithmic expressions without using a calculator if possible. 9 log 3 VX + 2 9 log 3 VX + 2The following function is given. f(x) = x3 - 5x2-9x + 45 a. List all rational zeros that are possible according to the Rational Zero Theorem. (Use a comma to separate answers as needed.) b. Use synthetic division to test several possible rational zeros in order to identify one actual zero. One rational zero of the given function is (Simplify your answer.) c. Use the zero from part (b) to find all the zeros of the polynomial function. The zeros of the function f(x) = x -5x - 9x + 45 are (Simplify your answer. Type an integer or a fraction. Use a comma to separate answers as needed.)Find the domain of the logarithmic function. f(x) = log (2 - x) The domain of f(x) = log (2 - x) is (Type your answer in interval notation.)Solve the system by the substitution method xy = 12 2x - y = -2 Select the correct choice below and, if necessary, fill in the answer box to complete your choice O A. The solution set is { (Type an ordered pair. Use a comma to separate answers if needed.) O B. There is no solution
