If (1, -3) is on the graph of f(x), which point must be on the graph of the inverse function f -1(x)?

If (1, -3) is the point of the function, then the point of the inverse function would be (-3, 1).

Firstly, the notation being used above with the negative 1 denotes that it is an inverse function. Secondly, all inverse functions are just the ordered pairs of the original function in reverse. So, since we had -3 for x and 1 for y, we change it to 1 for x and -3 for y.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
