In this mini-lesson you will learn how to find the range and domain of a function from its equation. The range of f is the set of all values that the function takes when x takes values from the domain. Let's take an example to understand this better. Let's say we have a function y = f(x) = x2
+ 3. As long as x is a real number, y is always going to be a real number as well, hence the domain of this function is x = R. Also, for all values of x, x2
is going to be 0 or higher, hence the range of this function, i.e. the value of f(x) ? 3.
