Find f^-1 (12) if x f(x)=3x-7

saveliy_v [14]

Answer:

The value of $f^{-1}(12)$ is $\frac{7}{-9}$ .

Step-by-step explanation:

The given equation is $x f(x) = 3x-7$ .

$f(x)=3-\frac{7}{x}$

The inverse of the function is found by adjusting the equation such that, expressing x in terms of f(x).

$\frac{7}{x} = 3 - f(x)$

$x = \frac{7}{3-f(x)}$

now, x = $f^{-1}(x)$ and f(x) be x.

Thus, $f^{-1}(x) = \frac{7}{3-x}$

Now, inserting value of x as 12,

$f^{-1}(12) = \frac{7}{3-(12)}$

$f^{-1}(12) = \frac{7}{-9}$
