hmm. do you know what x^3 looks like?

OpenStudy (anonymous):

no

geerky42 (geerky42):

do you have graph calculator?

OpenStudy (anonymous):

no, but i can see if there is one online

OpenStudy (anonymous):

okay i found one http://www.meta-calculator.com/online/?panel-101-equations

geerky42 (geerky42):

good, so you know x^3 looks like this:|dw:1399905305257:dw|

geerky42 (geerky42):

you do notice that one end goes to negative infinity and other one goes to positive infinity, right?

OpenStudy (anonymous):

yeah i did

geerky42 (geerky42):

so what do that mean for our roots?

geerky42 (geerky42):

how many roots can function with x^3 have?

OpenStudy (anonymous):

C

geerky42 (geerky42):

you think function can only have two roots?

OpenStudy (anonymous):

hmm

geerky42 (geerky42):

just to check, do you know what root is?

geerky42 (geerky42):

not actual roots, im asking you do you know what root means?

OpenStudy (anonymous):

opposite operation of applying exponents

geerky42 (geerky42):

lol, well, that's radical (square root or something) if you were asked to find root of function, they basically want you to find zero, or x-intercept. root is just another way to say zero or x-intercept.

geerky42 (geerky42):

so do you think this function still have two roots?

OpenStudy (anonymous):

ohh ok haha, and no i think its more than 2

geerky42 (geerky42):

ok, how many roots?

geerky42 (geerky42):
