1.	Consider the function f(x) = (√5x − 5) + 1.Which inequality is used to find the domain?
Answer» For the function f(x) = (√5x − 5) + 1, the domain isDf(x) ∈ [1,∞). Greater than equal to inequality is used to find the domain of the given function. The mathematical expressions in which both sides may or may not be equal are called inequalities. In inequality, unlike equations, we compare two values. The equal sign in between is replaced byless than,greater than,ornot equal tosign.
