Question

Pre-calculus 12 question!

Answer 1

Whats the question

Answer 2

One second

Answer 3

It is about relation and inverse of relation

Answer 4

What I am wondering is how the two lines in the graph are inverses of each other?

Answer 5

Do u understand the inverse function?

Answer 6

yes

Answer 7

If \((a,b)\) is a point on \(f(x)\), then \((b,a)\) will be a point on its inverse.

Answer 8

exactly

Answer 9

Next, recall the transformation rule for reflection over line \(y=x\) :

\[(x,y)\longrightarrow (y,x)\]

Answer 10

i dont understand. if you understand the inverse function, why wouldn't the graph make sense?

Answer 11

so, if two graphs are "symmetric" about the straight line \(y=x\), then they must be inverses of each other

Answer 12

I don't understand the shape of the graph, how can you tell if it is inverse?

Answer 13

oh I get it know @ganeshie8

Answer 14

lets do couple of quick examples maybe

Answer 15

sure

Answer 16

lets find inverse of below graph :
