can you graph anything with that domain and range?
|dw:1440551238566:dw| i was thinking something like this but i dont know if its correct
no it is not
if the domain is \((-\infty, \infty)\) you could just use \(y=x\)
i still dont get what your trying to say
why wouldnt it be curved
it just says graph anything right?
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
yeah thats correct what your telling me
it also ask to write the maximum and minimum for each one
can you post a picture or screenshot or something?
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
let me post it give me a sec
i sent you a pic of the question
lol i thought so !!
its number 2
you actually have a graph, don't you?
ok in that case it says pretty much what you said, but you missed "always increasing"
yeah srry about that my bad
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
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!
actually that answers both questions, the specific one and the general one
ok thank you for the help i can answer the rest on my own. just the graphing got me confused
also it means my second example above, the curvy one, is wrong, since it is not strictly increasing
ok got that but the straight one would be correct
yes it would
kk thx :)
