Question

if f(x) = 3x^2 - 2 , find the inverse and list any restrictions on the domain and range required to make it the inverse. help asap plz!!!

Answer 1

Hint: Make it \(y = 3x^2 - 2 \Longrightarrow x = 3y^2 - 2\) and solve for \(y\).

Answer 2

hey can u show me the work please ?
since im just reviewing for my final exam

Answer 3

You have:

\[\large x = 3y^2 - 2\]

Now add 2 both the sides and tell me what did you get..

Answer 4

You must do the work yourself, Abbey. I may give hints and examples.

Answer 5

2x=3y2-4?

Answer 6

For example, you may find out \(f^{-1}(x)\) in this case:\[ \color{Black}{\Rightarrow f(x) = 3 + x } \Longrightarrow x = 3 + y \Longrightarrow {x - 3 } = y \Longrightarrow f^{-1}(x) = x - 3\]

Answer 7

Nope. What did you do here?

Answer 8

im lost .

Answer 9

Where are you lost?

Answer 10

nick?

Answer 11

f(x)=y
y=3x^2-2
sqrt(y-2)/3=x
y>2

Answer 12

f^-1(x)=sqrt(y-2)/3

Answer 13

its a pre cal question
