Answer 3

The inverse of a function is fairly simple, all you do is solve for the other variable, so instead of have Y= all of that, you need to solve for X and have everything else on the other side

Answer 4

there @jigglypuff314

Answer 5

good, now Embryo has the right idea :)
flip the x and y and solve
so x = 7y^2 - 3 solve for y from there, do you know how?

Answer 6

no, and im in a hurry or else i wont make the deadline, ill just guess on it, thank you both though .....

Answer 7

add 3 to both sides
that should help you choose between C and D

Answer 8

That comment, that comment... (ﾉಥ益ಥ）ﾉ ┻━┻
Comments like that make me worry when i try to help, makes me wonder "do they even want to remember how to get this answer, or do they only want an answer and will ask again if they get the same question?"

Answer 9

\(\bf {\color{blue}{y}}=7{\color{brown}{ x}}^2-3\qquad inverse\implies {\color{brown}{ x}}=7{\color{blue}{y}}^2-3\)

solve for "y" to get the inverse "relation"

notice all we do is swap about the variables and then solve for "y"

Answer 10

that a little hard

Answer 11

in all honesty i dont want to remember how to solve it because this isnt something im going to need in life... i have to answer a few more questions and ill be done with the class and school for good. Ive had 18 hour days studying, writing 8 essays, 3 research papers, and taking exams on the human body. Just like some people are good in some areas and weak in others... I hate algebra yet i somehow have a B+ in the class.......
thank you though, i understand what youre saying, plus giving the answer to some people isnt always the best thing to do.

Answer 12

You can at least remember these steps,

To find the inverse:

Replace f(x) with y
Switch x's and y's, so put x where y is and x where y is.
Solve for y
Replace y with f^-1(x)

Answer 13

okay thank you @iambatman

Answer 14

i got it right,it was C
