Describe Domain
The domain is all the possible x-values/inputs of a fuction

what is a function?
A function is a relation where every x(input) value has exactly one y(output) value.

True or False:
f o g (x) = f(g(x))
True
200
describe range
The range is all the possible y-values/ outputs of a function

what is the domain of f(x)= sqrt(x)
[0,oo)

Is the relation a function?
{(1,5),(1,7),(3,9),(4,11)}
No, Because x=1 produces 2 inputs that are y= 5 and y=7.
