how to determine the range of a function Given the formula for a function determine the domain and range Exclude from the domain any input values that result in division by zero Exclude from the domain any input values that have nonreal or undefined number outputs Use the valid
The range of a function is the set of all possible outputs the function can produce Some functions like linear functions can have a range of all real numbers but lots of functions have a more limited set of possible outputs How to find the range The range of a function is the spread of possible y values minimum y value to maximum y value Substitute different x values into the expression for y to see what is happening Ask yourself Is y always positive Always

In this tutorial we ll cover the step by step process to determine the range of any function From linear to quadratic and beyond we ll explore the different types of functions and how to How to Find Range Learning how to find the range of a function can prove to be very important in Algebra and Calculus because it gives you the capability to assess what values are reached by a function Or in other words it allows you to find the set of all the images via the function
To find the domain of a function just plug the x values into the quadratic formula to get the y output To find the range of a function first find the x value and y value of the vertex using the formula x b 2a Then plug that answer into the function to find the range To find the domain and range of an equation y f x determine the values of the independent variable x for which the function is defined To calculate the range of the function we simply express the equation as x g y and then find the domain of g y
