Respuesta :

Domain is all real numbers or infinty.

Answer:

(-∞,∞)

Step-by-step explanation:

[tex]f(x) = 5x – 7[/tex]

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 : (-∞,∞)
