What is the basic DIFFERENCE, in terms of definition, between the domain and range of functions?
I am looking for simple terms NOT MATH BOOK jargon.

Domain is what you put into the equation, range is what you get out.

The domain is the values that x can take on.
The range is the values that y can assume.
For example in the function y = 3x + 4, x can be any real number so its domain is -infinity
If the function is y=x^2 the the domain is all the reakl numbers.
But the range is y>= 0 since y can never be negative.
If the function is 1 /(x-1) then x cannot be 1 because that would result in division by zero. Hence the domain is all real numbers except 1.

domain is the x values and range is the y values. The domain numbers are substituted into an equation and the range is the result/answer.

Domain is usually the area covered of the condition
range refers to the limit of values usually linear
