Answer:

The Domain : {(−∞,∞), {x/x∈R} and Range : {(−∞,∞), {y/y∈R} of the function f(x)=2x-5

What is a function?

A relation is a function if it has only One y-value for each x-value.

We have to find the domain and range of f(x)=2x-5

The domain of the expression is all real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined.

Interval Notation:(−∞,∞)

The range is the set of all valid y values.

Domain : {(−∞,∞), {x/x∈R}

Range : {(−∞,∞), {y/y∈R}

Hence, the Domain : {(−∞,∞), {x/x∈R} and Range : {(−∞,∞), {y/y∈R} of the function f(x)=2x-5

Have a wonderful day! :-)
