Question

If (-5,3) is on the graph of F(x), which point must be on the graph of the inverse fuction F^-1(y)?

A. (3,-5)
B. (-5,3)
C. (5,-3)
D.(-3,5)

Answer 1

From what we've been working on with inverse functions, you should have two ways to easily figure this one out.

1. Draw (-5,3) and remember the drawings I did with input/output for the original and inverse functions

2. Consider (-5,3) in terms of (x,y) and remember that if the original function sends x to y, the inverse sends y to x (swap the variables.)

Answer 2

Also, remember that question where I did the drawings; we decided that the original and inverse functions have reversed domains and ranges.

Answer 3

So would it be: 3,-5

Answer 4

Correct!

Answer 5

YAYYYYY THANK YOU

Answer 6

Np.

Answer 7

The correct answer is A. Because inverse functions usually have the flipped domain and rage of the original function.
