What is the domain of f(x) = 5x – 7?

a){x | x > –7}
b){x | x < –7}
c){x | x > 0}
d){x | x is a real number}

Option D is correct.

Step-by-step explanation:

we are given a function, f(x)= 5x - 7

We have to find the the domain of the function..

Domain of a function is set of point where the function is defined or value of the function exist.

Clearly, Function f(x) exist for every value of x or we get value of f(x) for every value of x.

⇒ Domain of f(x)={ x | x is a real number }

Therefore, Option D is correct.

b.my answer is b.
