Domain And Range Of Y X 4
Implies range rr 0 where rr is set of all real numbers.
Domain and range of y x 4. Rational function is undefined when denominator becomes zero. The domain is all values of that make the expression defined. Find the domain and range y 4 x. As a function table and as a set of coordinates.
Implies y is undefined when denominator x 4 0. Set the denominator in equal to to find where the expression is undefined. Implies this function is defined for all real numbers except 4. The range is the set of all valid values.
In this case there is no real number that makes the expression undefined. The domain and range of a function is all the possible values of the independent variable x for which y is defined. To find the domain or range solve for a variable and see if the other variable has any restrictions on it. Implies domain rr 4 this function can have any real value except zero.
Find the domain and range y square root of x 4 y x 4 y x 4 set the radicand in x 4 x 4 greater than or equal to 0 0 to find where the expression is defined. In this case x2 y 4 y 4 x2 there are no restrictions on x therefore x is in. The example below shows two different ways that a function can be represented. Implies y is undefined when denominator x 4.
Find the domain and range y x 4 y x4 y x 4 the domain of the expression is all real numbers except where the expression is undefined. The range of a function is all the possible values of the dependent variable y.
