How do you find the domain and range of #f(x)= sqrt(4-x^2) /( x-3)#?
1 Answer
Domain
Range
Explanation:
Domain is quite evident that
For finding the range, consider the domain from which it can be seen that y would never have any positive value and at end points +2, -2 it is 0, hence
Next square both sides, so that it is a quadratic equation in x,
For a function Real to Real
The range of the function would this be
