Graph the function f(x) = –3x3 + 9x2 – 2x + 3 using graphing technology and describe the end behavior. (1 point) Graph the function f(x) = x4 – 7x3 + 12x2 + 4x – 12 using graphing technology and describe the end behavior. (1 point) Without using technology, describe the end behavior of f(x) = –3x38 + 7x3 – 12x + 13. (1 point) Using complete sentences, explain how to find the zeros of the function f(x) = 2x3 – 9x + 3. (2 points) Create your own polynomial with a degree greater than 2. Attach the graph to the word document and find the zeros of the function. (3 points)
the end behavior is what happens with the graph when x grows so much this is x->INF
how do I put that into a sentence though?
u must write something like this "Down" on the left and "up" on the right.
okay, so i just describe how the line curves and stuff?
mmm yes but make the first one to make sure that u r doing it right
so this is the graph and I would say something along the lines of: the function starts in the upper left of the graph and at (0,3) it curves up until at (1,11) it curves back down into the bottom right?
does that make any sense?
mmm no just the end behavior for this graph it is up on the left and down to the right
i dont understand, sorry
see what happens when x is negative
the graph goes upward right¡?
and what happen when x is positive and grows so much
it extends downward?
yes so did u get it now? it is donw to the right
is that all i say?
yes it is what u need to say
okay, I understand. thank you!
ok any question write it here
