Question

Find a simple basic function as a right/left end end behavior model f(x)=e^x-2x

Answer 1

okay

Answer 2

u get this one already??

Answer 3

y = e^x - 2x

Answer 4

i need help with this one i dk wht to do

Answer 5

do you know what to do ?

Answer 6

think about e^x

Answer 7

for larger values of e^x does the linear line 2x values really matter

Answer 8

no

Answer 9

but for small values of x
e^x - x will start to matter
and for e^x where x is negative

Answer 10

e^x will get smaller and smaller while 2(-x) will stay about the same

Answer 11

ok? but were does this all lead to the point about left n right end?

Answer 12

here u can probably benefit from this, just dont rely on this for all your answers try to understand it!

Answer 14

yea that is what i want to do learn it

Answer 15

im basically saying for values of x as you go right the e^x is dominant and as you go toward the left, the -2x is dominant

Answer 16

oo i get that part now but what does simple basic form

Answer 17

how do you get that

Answer 18

as really big values of x, ull only see the effects of e^x
at really small values(more and more negative) of x, you will only see only -2x as e^-big number = approaching 0

Answer 19

e^-inf = 1/e^inf = 0
