Question

In which direction does the left side of the graph of this function point?
f(x)=-x^4-x^3+4x-2

Answer 1

and the right side?

Answer 2

so left is -6 and right is 6?

Answer 3

Does it go down as you go left, or up?

Answer 4

so left is -6 and right is 6?

Answer 5

down

Answer 6

No it's not asking for numbers... see the question "In which DIRECTION does the left side of the graph of this function point?"

Answer 7

so it goes down to the left and to the right

Answer 8

The reason is because x^4 will be positive when x is some large negative number... but -x^4 makes it negative

so as x approaches negative infinity, y approaches negative infinity

Answer 9

and as x approaches postive infinity, y approaches negative infinity

Answer 10

perfect thank you
