Which of the following graphs represents the function f(x) = x4 − 2x3 − 9x2 + 2x + 8?

For this case we have the following function:

We can rewrite the function as follows:

Therefore, the cut points of the function with the x axis are given by:

We observe then that the following graph corresponds to the given function. (See attached image)

5/12, or 5: 12

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
