Question

if f(x)={(3,5),(2,4),(1,7)}, find f^-1(x)

Answer 1

I think U are asking about the inverse... So in the inverse of any function...... The elements in the ordered pairs are interchanged, domain changes to range and range changes to domain,,,,,,,

Answer 2

In the inverse, the \(\textbf{domain}\) becomes the \(\textbf{range}\), and the \(\textbf{range}\) becomes the \(\textbf{domain}\).

Answer 3

how do you simplify it?

Answer 4

To give you an example:\[f(x) = \{(1,2), (3,4) \} \implies f^{-1}(x) = \{(2,1), (4,3) \} \]

Answer 5

Does that example help?

Answer 6

yeah. thank you
