Best ResponseYou've already chosen the best response.0so use the intermediate value theorem. at 1, the function = 6. at 0, the function = 4. since the function is continuous, it must pass the xaxis in the interval 1 to 0. at that point, you have the root. hope this is helpful

Best ResponseYou've already chosen the best response.03(1)^3  2(1)^2 + 5(1) + 4 3(1)  2(1)  5 + 4 3 2 5 + 4 6 3(0)^3  2(0)^2 + 5(0) + 4 3(0) 2(0) + 0 + 4 0 + 0 + 0 + 4 4 because at x = 1 , y = 6 and at x = 0, y = 4 the graph had to cross the x axis so there must be a root there.
