i need help graphing this, can someone help. The domain is negative infinity < x < + infinity and has a range of negative infinity < y< + infinity.

HI!!

- misty1212

can you graph anything with that domain and range?

no it is not

- misty1212

if the domain is \((-\infty, \infty)\) you could just use \(y=x\)

- lexy148

i still dont get what your trying to say

- misty1212

|dw:1440551451386:dw|

- lexy148

why wouldnt it be curved

- misty1212

it just says graph anything right?

- misty1212

you can make it curved, but it has to have domain all real numbers, your picture did not

maybe i do not understand the question
seems very open ended

- lexy148

yeah thats correct what your telling me

- lexy148

it also ask to write the maximum and minimum for each one

- misty1212

can you post a picture or screenshot or something?

- misty1212

i think there is more to the question than "graph anything with domain and range all real numbers"
maybe i am wrong, but it seems to open ended
besides, who ways it has a max or min
also you wrote "each one" like there could be several

- lexy148

let me post it give me a sec

i sent you a pic of the question

- misty1212

lol i thought so !!

- lexy148

its number 2

- misty1212

you actually have a graph, don't you?

- misty1212

oooh

- misty1212

ok in that case it says pretty much what you said, but you missed "always increasing"

- lexy148

yeah srry about that my bad

- misty1212

ok so we can use a specific example of a function that is always increasing
why make it hard, use \(f(x)=x\)
that has domain and range all real numbers, and is strictly increasing

- misty1212

Q) does your function have any max or min?
A) NO, if it is strictly increasing, it cannot have a local max or min because it keeps going up!

- misty1212

actually that answers both questions, the specific one and the general one

- lexy148

ok thank you for the help i can answer the rest on my own. just the graphing got me confused

- misty1212

also it means my second example above, the curvy one, is wrong, since it is not strictly increasing

- lexy148

ok got that but the straight one would be correct

- misty1212

yes it would

kk thx :)
