heres my home work for tonight.. can anyone tell me what i'm suppose to do? For this assessment, you will be graphing functions both with and without graphing technology. For the functions that are graphed without graphing technology, please show your work including the tables and graphs. To send a picture of the graphs from GeoGebra, go to the “File” menu at the top of the screen. Then select “Export” and “Graphics View to Clipboard.” Paste this picture in your document file. If another form of graphing technology is used, please include a picture of the graphs. 1. Graph the function f(x)

OpenStudy (anonymous):

what's the function?

OpenStudy (anonymous):

1. Graph the function f(x) = (x + 3)3 by hand and describe the end behavior. (1 point) 2. Graph the function f(x) = –x4 – 4 by hand and describe the end behavior. (1 point) 3. Graph the function f(x) = –3x3 + 9x2 – 2x + 3 using graphing technology and describe the end behavior. (1 point) 4. Graph the function f(x) = x4 – 7x3 + 12x2 + 4x – 12 using graphing technology and describe the end behavior. (1 point) 5. Without using technology, describe the end behavior of f(x) = –3x38 + 7x3 – 12x + 13. (1 point) 6. Using complete sentences, explain how to find the zeros of the function f(x) = 2x3 – 9x + 3. (2 points) 7. 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)

What part of the assignment are you having problems with?

OpenStudy (anonymous):

the whole thing, dont know how to graph that and i dont know what t means by hand or the end behavior?

OpenStudy (anonymous):

"By hand" means you need to graph it yourself on a piece paper

OpenStudy (anonymous):

End behaviour is how the function, suppose its f(x), behaves as x approaches positive infinity or negative infinity.

OpenStudy (anonymous):

can you show me how to do one of them

OpenStudy (anonymous):

Plug in test values of x and see what y gives you, then plot it on the coordinate plane. example for number 1: When x=1, y= (1+3)3 = 12 ---> (1,12) When x=2, y= (2+3)3 = 15 ---> (2,15) from this you can see the graph is a line, with a slope of 3/1 (It rises 3 and runs 1)

OpenStudy (anonymous):

The end behavior is how the graph acts towards the ends of the graphs (as x gets really large and very small)
