Solve the following cubic equation for three roots: 2x3 - x 2 - 18x90 Express your 3 answers as a decimals to the nearest tenth, in the order from smallest to largest value. Roots can be repeated! Show a sign only if the answer is negative. Solution: x = x = x = A/ A/ A/ Given the following function, use the Multiplicity Test to predict the behaviour at the x-intercepts f(x)=x(x+3)(x-2) (-2,0) touch, (0,0) touch, (3,0) touch (-2,0) cross, (0,0) cross (3,0) cross (-3,0) touch, (0,0) cross, (2,0) touch (-3,0) cross, (0,0) cross, (2,0) cross When fully factored, the following polynomial has four factors. Choose which four factors give the correct factoring of: f(x)=x3+4x+5x -1 X (x-1) (x + 1) (x-2) (x+2) (x-3) (x+3) (x-4) (x+4) (x-5) (x+5) For the following polynomial function, factor and find the coordinates of the x and y intercepts. p(x) = x+x4 Your answer should be submitted with no spaces between any characters. In the case that you have more than one intercept you should place a comma between each and order them in numerical order (smaller to larger value). If roots repeat, only state them once. For example, if you were wanting to input three x intercepts that occur when x = 5, x = -10, and x = 0 you would submit your answer as: (-10,0),(0,0),(5,0) y-int = x-int(s) = A/ Give the following function, use the Leading Coefficient Test to find the leading term of p(x) p(x)=x(x+2)(x-3) x -6x3 -6x 3
