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 : (-∞,∞)
