The range is the set of all valid values.
Domain and range y x 3. The range of a function is all the possible values of the dependent variable y. Here are some examples illustrating how to ask for the domain and range. To avoid ambiguous queries make sure to use parentheses where necessary. The domain of all polynomials is all real numbers so the domain of.
Enter your queries using plain english. The domain of a function is the collection of independent variables of x and the range is the collection of dependent variables of y. Find the domain and range y x 3. Y x 3 is all real numbers.
The domain of the expression is all real numbers except where the expression is undefined. To find the domain of a function just plug the x values into the quadratic formula to get the y output. The domain and range of a function is all the possible values of the independent variable x for which y is defined. Find the domain of 1 e 1 x 1 function domain.
While the range is the set of all possible output values usually y which result from using the function formula. The domain is all real numbers. In this case there is no real number that makes the expression undefined. If the function were y x 2 then the range would have been all reals greater than or equal to 0 since the negative numbers squared would give positive results.
Pre calculus function domain calculator menu pre algebra order of operations factors primes fractions long arithmetic decimals exponents radicals ratios proportions percent modulo mean median mode scientific notation arithmetics. The example below shows two different ways that a function can be represented. Since every number has a real cube root and it is unique the range of the function is also all real numbers. So in this case the range will be all real numbers as well.
Y x is all real numbers. In this case there is no real number that makes the expression undefined. Since you can take the absolute value of all real numbers the domain of. Domain of log x x 2 1 x 2 1 domain.
