Question

Find the inverse of this function, please show work.
(-2x+7)/x

I keep getting 7/3x, can you tell me where I'm going wrong?

Answer 1

let f(x) = (-2x+7)/x

so f^-1(x) would be 7/(x+2)

Answer 2

But how?

Answer 3

You do the opposite function in such a way to where it would negate the equation.

If you add x, you subtract. However, you have to do it in order.

Answer 4

*if you add x, you subtract x

Answer 5

I get stuck at xy+2y=7

Answer 6

factor out y
