Question #93df1

Answer 1

1. `y=348`
   2.:`y=x`

Explanation:

As you may know, if we take the inverse of a function (`f^(-1)(x)`), we flip the function over the line `y=x` producing two mirror images on either side.

Using this, we know that if we put an inverse function into a function, it will cancel out to just give `x`, this is because when we take the inverse of a function, we find `x` in terms of `y` then switch the letters around. For example, if `y=f(x)=-15x+22` then `f^(-1)(x)=x=-15y+22` so `f^(-1)(x)=(x-22)/(-15)`

The equations cancel as you are cancelling what you did to make `f(x)` become `f^(-1)(x)`.

If `y=f(x)=x`, then `f(348)=348`

The equation in terms of `x` is `y=x`
