#how do i find the range for a function?

@umbral atlas the range of a function is the set of all outputs. So you are given that set domain, {-4,1,3} and, for each function, you want to find that set.
This wording is a bit confusing though.. A more clear way (imo) of describing what you're meant to do is, "Given this set of inputs (the domain), find the image of each element under the given function"
Okay, what do you know about the question that it's asking? How are you interpreting it?
i dont know anything
like my teacher taught me this
but then this shows something complettly different
like how do i plug the equation in
Do you understand what a set is?
no
oh wait
do i set up the eqaution
like this
y = -4 + 7
for number 1
also y = 1 + 7
and y = 3 + 7
Yes. But do you know what to do with the y values you end up getting after plugging in those domain values?
Weird
wait so then what do ido after
i guess thats not a huge problem. they probably just want you to make a graph where you put a point on the graph for each input and its output
so making an ordered pair (input, output) and showing where it lives on the graph of the function
is the ordered pay -4,3
pair*
for the first one
1,8 for the second
and 3,10 for the third
Yes
ok then i graph it
Yes
how do i do number 2
What do you mean
Same thing
and looks weird
plug in the values of the domain
and record the outputs
that set of outputs is the "range"
ok thank you
you're welcome
