# What is the domain of f(x) = 5x - 7?

{x | x > -7}, {x | x < -7}, {x | x > 0}, {x | x is a real number}

**Solution: **

The domain is the set of all the input values given to a function.

The domain of any expression is set to all the real numbers, except where the expression is undefined.

In the expression f(x) = 5x - 7, the domain is all real numbers.

The graph of the function will be a straight line without discontinuities.

The domain of f(x) = 5x - 7 is {x | x is a real number} and this can be denoted as ( - ∞, ∞) for all x ∈ R.

## What is the domain of f(x) = 5x - 7?

{x | x > -7}, {x | x < -7}, {x | x > 0}, {x | x is a real number}

**Summary:**

The domain of f(x) = 5x - 7 is {x | x is a real number} can be denoted as ( - ∞, ∞) for all x ∈ R.
