if (-3,7) is on the graph of f(x) which point must be on the graph of the inverse function f^-1(y)

Question

ajspeller · Answer

Switch the x and y coordinates.

anonymous · Answer

I suck at these

anonymous · Answer

so (-7,3) or would it be (3,-7) @ajspeller

danjs · Answer

The inverse of the function, is the function reflected over the line y=x on the coordinate plane

anonymous · Answer

so it would be (3,-7) then right? @DanJS

anonymous · Answer

im confused :(

danjs · Answer

it is the reflection over the line y=x

anonymous · Answer

so its (3,-7)?

danjs · Answer

right

anonymous · Answer

okay that graph helped a lot thank you!

danjs · Answer

welcome

danjs · Answer

FOr an entire function... every point is reflected over

anonymous · Answer

actually... its (7,-3)

danjs · Answer

o crap, you are right, i messed that up, just switch the x and y coordinates for a single point

danjs · Answer

The inverse of a function has all the same points as the original function, except that the x's and y's have been reversed
