F(x)=
then what is f^-1(x)

To find f-¹(x) of f(x) equate f(x) to y

That's

f(x) = y

So we have

Next interchange the variables that's x becomes y and y becomes x

That's

Next make y the subject

Cross multiply

We have

4y - 7 = 10x

Move -7 to the right side of the equation

4y = 10x + 7

Divide both sides by 4

We have the final answer as

So

Hope this helps you

4+4+2x

or

2x+8
