which of the following describes the function x^3-8? a) The degree of the function is odd, so the ends of the graph continue in opposite directions. because the leading coefficient is positive, the left side of the graph continues down the coordinate plane and the right side continues upward b) The degree of the function is odd, so the ends of the graph continue in the same direction. Because the leading coefficient is negative, The left side of the graph continues down the coordinate plane and the right side also continues downward.

Have you tried graphing it on a calculator?

c) The degree of the function is odd, so the ends of the graph continue in opposite directions. Because the leading coefficient is negative, The left side of the grass continues up the coordinate plane and the right side continues down more The left side of the graph continues up the coordinate plane and the right side continues downward. d) The degree of the function is odd, so the hands of the graph continue in the same direction. Because the leading coefficient is positive, the left side of the graph continues up the coordinate plane and the right side continues upward

you don't really need to see the graph because b says the "leading coefficient is negative" and it isn't

ends* not hands. and no, that's probably a good idea though
anonymous
  • anonymous
but that doesn't really tell me whether the leading coefficient is positive or negative
anonymous
  • anonymous
so the leading coefficient is positive? that narrows it down to a or c

the leading coefficient is the coefficient on the leading term (x^3) since there isn't a number, it's just 1(positive 1) you're right it narrows it down to a or d a) The degree of the function is odd, so the ends of the graph continue in opposite directions. because the leading coefficient is positive, the left side of the graph continues down the coordinate plane and the right side continues upward d) The degree of the function is odd, so the hands of the graph continue in the same direction. Because the leading coefficient is positive, the left side of the graph continues up the coordinate plane and the right side continues upward now you need to know behaviors of graphs, stuff like y=x^2 (even degree) |dw:1447430757352:dw| whereas odd degree polynomials look like|dw:1447430805919:dw|

yeah I meant a or d. but I'm confused where did Y=x^2 come from
bibby

just as an example, because I was looking at the very first sentence in both choices. a) The degree of the function is odd, so the ends of the graph continue in opposite directions. what that looks like is this |dw:1447431022900:dw| d) The degree of the function is odd, so the hands of the graph continue in the same direction. whereas "continuing in the same direction" means |dw:1447431045521:dw|

oh okay I understand what you're saying
bibby

so which one are we going with?
anonymous

D?
anonymous
  • anonymous
idk I'm still very confused. D looks right lol
bibby
  • bibby
lol, sorry I suck at explaining things uhhh here firstly, look at the graph now understand what the difference between a and d is the "hands" are the draggy parts with the arrows where the graph continues on to infinity. so: "the hands of the graph continue in the same direction" |dw:1447431396995:dw| versus "the hands of the graph continue in the opposite direction" |dw:1447431433489:dw|

I attached the graph in the bottom of the post

okay well now I 100% am able to see why it's A and understand why so I think I got it :)

yayyyyyyyyyy
