Graph the function f(x) = –x^3 + 2 Use complete sentences to explain the process of graphing f(x) = –x^3 + 2 What is the end behavior of f(x) = –x^3 + 2 ?

we know that the graph of x^3 is

im so confused on this question. its rediculous... :(

now the graph of -x^3 will be

8. rizwan_uet

adding 2 to the graph we get

now form the final graph we can see the end behavior that when x approaches to +infinity f(x) approaches to -infinity and when x approaches to -infinity f(x) approaches to +infinity

okk. thankyou..can you explain in words the process of graphing? im still kind of confused even after seeing your drawings (which were excelent and clear btw, which i really appreciate)

12. rizwan_uet

ok

13. rizwan_uet

take the equation f(x)= -x^3+2 put x= 0 in it we get f(0) = 0+2 = 2 we got this point (0,2) plot this point now start putting positive values (1,2,3,4,....) in x and compute f(x) now put negative values(-1,-2,-3,-4,.....) in x and compute f(x) you will get many points in this way plot all those points on a graph paper and you are done

thankyou soo much you have no idea how hard this is for me. i have one more question if you wouldnt mind answering it..i will post it as a new question if you are willing to give it a shot?

15. rizwan_uet

sure

16. itsjustme_lol

ok i will post it in a second..thank you
