Question

Can someone plz help
What is the end behavior of f(x) = –x3 + 1?

Answer 1

is that
\[ f(x)= -x^3 + 1 \]

if so what do you get when you put in a big positive number for x
example if x=1000, what is - 1000*1000*1000+1
as x gets bigger what is f(x) doing ?

Answer 2

then put in a very negative number for x, example x= -1000
what is
- (-1000)*(-1000)*(-1000) + 1 ?

Answer 3

it becomes positive?

Answer 4

there are two "ends" one where x-> + infinity.
and the other where x -> -infinity

for x->+ infinity , what is f(x) doing ?
example if x=1000, what is - 1000*1000*1000+1
