Question

Which function below is the inverse of f(x) = The quantity of two x plus three, over five.?

f−1(x) = The quantity of five x plus three, over two
f−1(x) = The quantity of five x minus three, over two
f−1(x) = Five over the quantity of two x plus three
f−1(x) = Five over the quantity of three minus two x

Answer 1

Hint:
one of the properties of inverse functions is
\(f^{-1}(f(x))=x\)
so you have a choice of finding the inverse and match the answers, or use the property above to check each choice.
