Which statement best describes the graph of -x3 - x2 + 4x + 4?

t starts down on the left and goes up on the right and intersects the x-axis at x = -2, 2, and 4.

It starts down on the left and goes up on the right and intersects the x-axis at x = -2, -1, and 2.

It starts up on the left and goes down on the right and intersects the x-axis at x = -2, -1, and 2.

It starts up on the left and goes down on the right and intersects the x-axis at x = -2, 2, and 4.

Do you know what $y=x^3$ looks like?

fairy733189 · Answer

no I don't

it looks like this

|dw:1463894946862:dw|

When we multiply this by - then we are reflecting that across the $x$ axis. So $-x^3$ looks like this

|dw:1463895036457:dw|
