Best ResponseYou've already chosen the best response.1we could try the factor theorem like if f(1) = 0 then x  1 is a factor but that can be a bit tediuos

Best ResponseYou've already chosen the best response.1try 1 and 1 but thats no good have you got a list of options?

Best ResponseYou've already chosen the best response.1f(2) = 0 so that makes (x  20 a factor

Best ResponseYou've already chosen the best response.0Describe the graph of the function f(x) = x3 − 15x2 + 68x − 96. Include the yintercept, xintercepts, and the end behavior.

Best ResponseYou've already chosen the best response.1the yintercept is easy its value of y when x = 0 = 0  0 + 0  96

Best ResponseYou've already chosen the best response.1you need to factor it to find the x  intercepts

Best ResponseYou've already chosen the best response.1we can try factoring by look at factors of 96

Best ResponseYou've already chosen the best response.1factor out the function we get (x3)(x4)(x8) now let each bracket equal 0 and solve for x

Best ResponseYou've already chosen the best response.12*2*2*2*2*3 (x 3) might be a factor f(3) = 0 so that one  oh LynFran has done it already

Best ResponseYou've already chosen the best response.0so which one of the 3 is my answer?

LynFran

Best ResponseYou've already chosen the best response.1all 3 are the x intercept

Best ResponseYou've already chosen the best response.1@LynFran = please explain how you got that . Openstudy advises us to guide the poster to the answer

Best ResponseYou've already chosen the best response.1lets look at the highest root which is 8 the graph passes through this point (8,0) so we need to look at what hapenns to f(x) for x > 8 find f(9) and f(10) f(9) = 30 f(10) = 84  the graph is rising towards infinity at the endpoint

Best ResponseYou've already chosen the best response.0so the answer is infinity?

Best ResponseYou've already chosen the best response.1I was wondering how LynFran was factoring the function so quickly  she was using software to do it for her! Thats no way to learn math  you cant use software in an examination.
