If F -1(x) is the inverse of F(x), which statements must be true?

The inverse function, denoted F^{-1}(x), of a one-to-one function F(x) is defined as

F^{-1}(x) = \{(y,x) | \text{ such that } y = f(x)\}.

Main properties:

1. F(F^{-1}(x)) = x, x in the domain of F^{-1};

F^{-1}(F(x)) = x, x in the domain of F.

2. The domain of F is equal to the range of  F^{-1} and the range of F is equal to the domain of  F^{-1}.

From these properties you can state that options B, C, D and E are true and points A and F are false.

Please help! 20 pts.
Daniel [21]
Your answer would be the last option, 80 cm.

As this is a right triangle, you can use Pythagoras's Theorem, a² + b² = c², where 'c' is the hypotenuse and 'a' and 'b' are the legs, to find the missing side.

This gives us:

48² + 64² = 2,304 + 4,096 = 6,400
√6,400 = 80

So 80 is your answer.

I hope this helps!

Help please idk what im doing wrong
Musya8 [376]
From what I can see, you are on the right track.

one thing you could have done is combine like terms.
{10}^{2}  -  {3}^{2}  =  {7}^{2}

Now just take the square root of 7 squared. That takes out the squared making your answer 7 or G.

You were on the right track, you just skipped a step.

hope this helped!
