Let f(x)=7x-13. Find f^-1(x).

Ok but allow my humble self to use instead of .

We have,

If you wanna know what the inverse is swap the values of x and y,

And now solve for y,

.

Hope this helps.

The inverse function is (x+13)/7

Step-by-step explanation:

y = 7x-13

Exchange x and y

x = 7y -13

Solve for y

Add 13 to each side

x+13 = 7y-13+13

x+13 = 7y

Divide each side by 7

(x+13)/7 = 7y/7

(x+13)/7 = y

The inverse function is (x+13)/7

the two may have that, even a breakdown is probably offered
