Question

which description means the same thing as this limit expression?
lim f(x)= -infinity
x -> - infinity

the graph falls on the left side
the graph falls on the right side
the graph rises on the left side
the graph rises on the right side

I think the answer is the graph falls on the left side

Answer 1

Answer 2

Limit as x goes to -infinity is - infinity

Answer 3

okay?

Answer 4

yeah, just doesnt say much about anything, but it does mean as you go towards -infinity in x values, the y values go towards -infinity also.

Answer 5

lol but how does that get you to the answer. I get what your saying though.

Answer 6

`I think the answer is the graph falls on the left side`

I agree. As x heads off to the left side, the function decreases off to -infinity

Answer 7

thats what i thought @jim_thompson5910

Answer 8

yes, if you start anywhere, the end behavior on the left side of the function is to fall lower forever as you move more left

Answer 9

thank you
