To find the domain of the function, find the values of the variable that will give a real range.
To find the range of the function, find the result when plugging or substituting the values of the variable that are in the domain in the function.
Mathlish? You mean in words?
Like, domain of f is all values of x from, but not including, x=2, up to x=6.
Domain is x = (2,6].
Domain is 2 < x <= 6. ----------I'm not sure of this.
I always like to state the domain in words. I am sometimes lost with all these many Math symbols.
