Question

:)

Answer 1

Domain is the numbers you can use
range is the result of inputing the domain

an interesting fact is that the inverse of a function switches the domain and range

basically
the domain of f(x) becomes the range of f^-1(x)
the range of f(x) becomes the domain of f^-1(x)
so just find the domain and range of f(x)


$f(x)=3x- \frac{1}{2}$
there are no restrictions
all real numbers can be used
all real numbers can result


so the answer is domain and range for both is all real numbers
