Question

What is the domain of f(x) = 5x – 7?

Answer 1

Domain is all real numbers or infinty.

Answer 2

(-∞,∞)

Explanation:

`f(x) = 5x – 7`

Domain is the set of all x values for which the function is defined.

f(x) is a linear function. For linear function there is no restriction for x.

For all x values , we will get the value of y

So , domain is the set of all real numbers

Domain take values from - infinity to infinity

Domain : (-∞,∞)
