Question

domain and range of 3x-2

Answer 1

Find the Domain and Range y=3x-2

y=3x−2y=3x-2

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

Answer 2

Domain is a set of all possible values of the variable for which the function is defined.

if any other value out of the domain is taken ,the output can't be defined.

The set of all the outputs which are got putting the values from domain in function is called the range of the function.

We can't get any different output that is not exist in range by putting values from domain.

f(x) =3x-2 is defined for all real values of x. If we put any real value , the function will give us an output.

and it's range is also real numbers.

So it is defined from R to R.
