Question

What is the domain of f(x) = 5x – 7?

A)x
B) x < –7
C) x > 0
D)x

Answer 1

It's D, because when graphing the function, the line has no end haha :)
Hope it helped you!

Answer 2

Option D is correct.

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

Therefore, Option D is correct.
