(1) (a) List all possible rational zeros of the rational function: f(x)=9x' +22° -87-15x² + 3x + 20 (b) Find the zeros of the polynomial function and state the multiplicity of each. f(x)=(x+8) (r - 4)*(x+1)' (x –15)'(x+3)
The following function is given. f(x) = x3 – 5x² - 4x + 20 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....
Find all rational zeros of the function f(x)=2x'-9x'-6x+5. Find all rational zeros of the function f(x)=2x'-9x'-6x+5.
-----..on 12. The functions (*) s f(x) = 3x - 1 fy(x) = 4x and f(x) = 2x are linearly dependent. Show this by finding values of CC, and c,, not all zeros, such that ºf(x) + c, f(x) + e, f,(x) = 0.
show work, neat writting please and thanks! 9) Given: f(x) = x - 7x2 + 4x + 12 a) List some possible rational zeros. b) Use the Factor Theorem to determine if (x - 6) is a factor of f(x). (Yes or No? Show your work.) c) If (x - 6) is a factor, use synthetic division to find the other factors. List them here. d) List the zeros of f(x). C) Rational Functions: 10) Given the rational function: a)...
12.Find all the zeros of the polynomial function h(x) = 2x* - 9x + 16x2 - 27x + 30 a) List all possible rational zeros. b) Use synthetic division to show that is a zero of the given function. c) Find the remaining zeros.
answer all with clear handwriting please. 2. (4 points) Let f(x) = x - 9x - 36x”. Find the zeros of the function algehraically (by factoring). and give the exact multiplicity for each zero (not just odd/even). State the behavior of the graph at each zero (whether the graph crosses the x-axts or touches the x-axts and turns around at each zero). Zero Multiplicity Behavior 3. (4 points) Solve the following inequality and graph the solution set on a Real...
