9. Which of the following polynomial functions might have the graph shown in the illustration? a. f(x) = x*(x-4)*(x+3) b. f(x) = x(x-4)(x+31° C. f(x) = x°[x+4)*(x-3) d. f(x) = x(x+4)(x-3) e. f(x) = x(x-4)(x+3) 10. Find all zeros, real and complex, of the function f(x) = 3x +7x' +14x+28x + 8. a. 6.-2.-21,21} b. 6 -2,-2,2} C. (-3,-2 -21, 21) d. 6.2.-21, 21} e. (-3,-2, -2,2) 11. In the problem, t is a real number and P corresponds to t. Find csc t. - 9) is the point on the unit circle that doo

Answer 1

21 from the graph: -4 0 and 3 are the zeros of the polynomial. So ) and (d) are the possible polynomial. il o f(n)= n2ntajr (n-3) (d) floma (n+4) (0-32 Again from the graph, f'(og zo . f '(-4)=0 (snee the tangent at that point is parallel to nang). of has double roof at o and -u. Comect option is (e) ie fm = n2 (2+4) 2 (m+3). is the polynomial of the given graph.

(10 fm) = 3n" + 7 x3 + 14 27 4280 +8 The product of the zeross possible option (a) and (d. Dgain the sum of the roofs s / stence option (as is correct. 7. P=.09.-26) Cost = Sinit=-2178 eset = stot T2 - PURE
