Question

find the domain and the range of the function defined by f(x)=x-1/x+1​

Answer 1

Step-by-step explanation:

Set the denominator in x−1x+1 x - 1 x + 1 equal to 0 to find where the expression is undefined. Subtract 1 from both sides of the equation. The domain is all values of x that make the expression defined. The range is the set of all valid y values.
