If we drew the whole parabola...

and flipped him over the line
y = x using the "every (x, y)
has a (y, x)" thing...		 a graph Standard Parabola Guy

 

a graph of Standard Parabola Guy and it's mirror image across the line y = x ... the mirror image does not pass the vertical line test The result would fail the
vertical line test.  It's NOT
a function!

And what's the name
of this chapter? 

Inverse FUNCTIONS!

We only care about them
if they are functions.

(Harsh, but true.) 

 

YOUR TURN:

Graph the inverse of this function:

a graph of the function that passes through the points ( -4 , -2 ) , ( -3 , 0 ) , ( -1 , 1 ) , ( 0 , 3 ) and ( 4 , 4 )
