Question

Which of the following could represent the graph of f(x) = x4 + x3 – 8x2 – 12x?

Answer 1

The 2nd graph is the correct answer.

Answer 2

Answer:

The exact graph is attached.

To graph this functions we just need to give arbitrary values to x and calculate  each corresponding value to f(x).

In this case, we could use the following table:

x       f(x)

-2      0

-1       4

0       0

1        -18

2       -24

If you graph each pair, you will have  5 points, which once connected it will give you the graph attached.
