How to find domain and range of a function

How do you determine the domain of a function? To find the range of a function, you must first evaluate the terms of the equation. The quadratic function has the form ax 2 + bx + c: f (x) = 2x 2 + 3x + 4. Examples of functions with fractions: f (x) = (1 / x), f (x) = (x + 1) / (x1) etc.

How do you find the domain of a given function?

To find the domain of a function, you must list all possible numbers that the function satisfies, or all values of x. Rewrite the equation by replacing f(x) with y. This brings the equation into a consistent form and simplifies processing.
