#1) Domain is the set of values of x at which the function is defined.

The given function is f(x) = 5x – 7 a linear function.

There is no restriction for a linear function because a linear function is define at every values of x.

Therefore, domain of all linear function is all real numbers.

Therefore the correct choice is d) {x | x is a real number}.

For #2) Sequence is missing.
