Question

Which equation can be simplified to find the inverse of y=x^2-7?

Answer 1

Possible answers....

Answer 2

What do you think it is?

Answer 3

I'm not entirely sure. The unit that explained how to solve this equation was way back at the begging of the semester, so I'm kind of lost.

Answer 4

Ok, Try to solve it for me.

Answer 5

You mean find the inverse?

Answer 6

Follow the problem.

Answer 7

I'm sorry. I don't understand. :(

Answer 8

Yes, Find the Inverse

Answer 9

Ok, one minute.

Answer 10

y=x^2-7

Switch x & y:

x=y^2-7

Solve for y:

\[\sqrt{x}=\sqrt{y^2} -7\]
\[\sqrt{x}+7=y\]

Answer 11

Ok, From that what can you use to get the answer?

Answer 12

x=y^2-7 must be simplified to get the inverse of y=x^2-7 and that's the answer they want.

Answer 13

Is that right @WWWHHHAAATTT? ?

Answer 14

Do you think it is?
