Answer:

Step-by-step explanation:
The inverse of a function is when the x and y are swapped. So the first step is to write f(x) as y and then swap the x and y
Original Equation:

write f(x) as y (since that's what it represents)

Swap x and y

Square both sides

Add 1 to both sides

So this gives you the equation:

The distance of points P and B is 5
Ur close but it is 0.023 you were off just a bit
17
it's 17+(-7)=10
i hope that answers your problem
