# Let f (x) = √x − 1 and g(x) = 1x − 2 .(i) State the domains for f and g, and the range of f .

## Question

## Solution 1

(i)

The domain of a function is the set of all possible input values (x-values) which will output real numbers.

For the function f(x) = √x - 1, the input x must be greater than or equal to 1. This is because the square root of a negative number is not a real number. So, the domain of f is [1, ∞) Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
