how do you find the domain in 2/x^2+3?
Range: The range is the set of all possible output values , which result from using the function formula.
In this case when x = 0
2 / x ^ 2 -> infinity.
So domain : ( -infinity , 0 ] U [ 0 , infinity )
Or all value of x different of 0
Domain: The domain of a function is the set of all possible input values which allows the function formula to work.
