2. (15:1,2,2,5, 1,1,3) Let f (x) = 2x5 - 3x4 - 98x3+148x2 - 49. e. Write f(x) in factorized form. a. Use Descartes' rule of signs to find the possible number of positive real zeros. f. List the y-intercept and x-intercepts of b. Use Descartes' rule of signs to find the possible number of negative real zeros. f(x). c. Use the rational zeros theorem to determine the possible rational zeros of f(x ). g. Sketch the graph. Incorporate the x- intercepts (and the multiplicity of each) and y-intercept. You don't need to d. Find the zeros of f(x) by using the graph it to scale. candidates you get in part (c). Make sure you also mention the multiplicity of each zero at the end. Show only the work that gives you the zero
