Calculadora de função inversa

A calculadora encontrará o inverso da função fornecida, com as etapas mostradas. Se a função for um para um, haverá um inverso exclusivo.

Enter a function: $$$y=f(x)=$$$

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Your input: find the inverse of the function $$$y=\frac{x + 7}{3 x + 5}$$$

To find the inverse function, swap $$$x$$$ and $$$y$$$, and solve the resulting equation for $$$x$$$.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: $$$y=\frac{x + 7}{3 x + 5}$$$ becomes $$$x=\frac{y + 7}{3 y + 5}$$$.

Now, solve the equation $$$x=\frac{y + 7}{3 y + 5}$$$ for $$$y$$$.

$$$y=\frac{7 - 5 x}{3 x - 1}$$$


$$$y=\frac{7 - 5 x}{3 x - 1}$$$
