Find the domain and range of f(x)=1/x^2

Answer 1

The domain of f(x) is all real numbers except x = 0. This is because dividing by zero is undefined.

The range of f(x) is all positive numbers. This is because no matter what value of x you choose (except for x = 0), 1/x^2 will always be positive. As x approaches 0 from either side, the function approaches positive infinity.
