the domain is all real numbers but -1 and 1 right??

what about range?

range is in the y-axis... hmm.

range is always a pain >_<
but here's the graph of the function

i don't get it :/

we have the domain... which x is all reals except when x =1 and x =-1

?!

plug in x = -3/4 and you'll get y = 0

so the range is the set of all real numbers

how is the range all reals? I don't get that part..

oh wait.. unless the line is going through all y -values. ._.

yeah any y value is possible

wait i don't get it

it is all reals XD . My mind went blank . Why is domain easier to find than range?

oh!! i see it, thank you :)
can you also help me on finding the relative extrema for 2x^3+5x^2-25x?

alright but first we have to graph this

can we find it without graphing

relative extrema.. like maxs and mins.. (gonna be hard though without a graph )

nope haha im confused. i'm supposed to find it without equation i think

without the graph*

so you're not in a calculus course?

its precalc!

ok... do you know how to take derivatives?

weird you need those

i figured it out haha thanks :)
