Answer:

In the given expression, that is, f (x) = 5x - 7, we can say:

x satisfies all the real values starting from -∞ to ∞.

domain of 5x-7

Interval notation for f (x):

(- ∞ , ∞)

So, the domain will be all real numbers, as the function is a straight line, with no discontinuities, thus undefined at no value of x.
