F X X 2 3 X Find Domain And Range

Ex 2 3 2 find the domain and range of the following real function.

F x x 2 3 x find domain and range. Domain is all real numbers except x 4 the only limitation on the domain in this equation is undefined answers. Find the domain and range f x 3 the domain of the expression is all real numbers except where the expression is undefined. In this case there is no real number that makes the expression undefined. F x x here we are given a real function hence both domain and range should be real numbers here x can be any real number here f x will always be negative or zero.

In this case there is no real number that makes the expression undefined. Let y x 2 3 x 3 y xy x 2 x xy 3 y 2 x 1 y 3 y 2 x 3 y 2 1 y here 1 y 0 y 1 so range is r 1. All these are real values here value of doma. Find the domain and range of the real function f x x 1 x2.

Therefore the limitation can be described by denominator 0 or in this case x 4 0 so x cannot equal 4. Click here to get an answer to your question find the domain and range of f x x 1 3 x.
