Which of the following is an x-intercept of the function, f () = x3-5x2 - 8x + 48

Step-by-step explanation:

x^3 - 5x2 - 8x + 48 = 0

You haven't supplied a list. To confirm which value is the correct one substitute the values for x and see if the result is 0.

Since the last term is 48 you could try some of the factors of 48 : 1, - 1, 2, - 2, 3 - 3 and so on.
