Find the solutions to 0 > –(x – 2)3 by graphing y > –(x – 2)3

OpenStudy (anonymous):

the three is an exponent. help please.

ganeshie8 (ganeshie8):

graph the inequality function

OpenStudy (anonymous):

ya but how do you do that?

ganeshie8 (ganeshie8):

first graph y = -(x-2)3, then we can figure out the shading for inequality

|dw:1372765369247:dw| Is it going to look like this?

ganeshie8 (ganeshie8):

something like that... lets do it step by step

ganeshie8 (ganeshie8):

y = -(x-2)3 first notice that it has an odd degree

OpenStudy (anonymous):

yes so one side is going down and one up right?

ganeshie8 (ganeshie8):

yes ! thats the first observation

ganeshie8 (ganeshie8):

next, it has a - attached to to it, so its flipped version of y = x^3

ganeshie8 (ganeshie8):

meaning, as u go right, it goes down

OpenStudy (anonymous):

yes and when you go left it goes up
