Question

Says:

Determine the inverse functions for the functions below. Begin by switching variables in the original function, then solving for the 'new' y.

state the Invariant.

1. y=x^2

10 points!!

Answer 1

Cheater.  Do you own homework.

Answer 2

y = square root x

Answer 3

...my head hurts

Answer 4

There&#039;s actually two inverse functions for this problem.

y=sqrt(x) and y=-sqrt(x)

The invariant in this case is the vertex, as it does not change, despite the graph being rotated 90 degrees to the right.

Answer 5

dude, what type of math is this??

Answer 6

Here&#039;s a good explanation...

Answer 7

ummm

do u mean by inversing y = x^(2) ?

lols

ok, by inversing it, change y into x, &amp; x into y

i.e: x = y^(2)

making finding the eqn of y = ~~~~~~~~~~

square root (x) = y

therefore

y = (+ or -)x^(0.5)
