Question

What is the inverse of the given relation?

y = 7x2 – 3

Answer 1

basically solve for x and you will get inverse

Answer 2

... and then replace \(x\) with \(y\) and vice-versa.

Answer 3

f(x)=y=7x^2-3

Answer 4

You're all talking a foreign language to me. I hate math, more than anything. I don't get this, at all.

Answer 5

Hating it and getting it are two different things.

Answer 6

I hate it, and dont get it.

Answer 7

when i said "solve for x" i meant rearrange the terms so that x is by itself
\[y = 7x^{2} -3\]
add 3 to both sides
\[y+3 = 7x^{2}\]
...
until
x = ?

Answer 8

7^2 = 49, so 49x?

Answer 9

hmm no the 7 is not being squared, only the x

Answer 10

let me try this example...

5x = 4
what does x equal?

Answer 11

wouldn't i divide 5 by both sides?

Answer 12

thats right...ok now apply that concept to

y+3 = 7x^2

Answer 13

or
7x^2 = y+3

if that looks nicer
