Question

HELP ME


If g(x) = 3x - 5, then g -1(x)=

Answer 1

first find the inverse.

Answer 2

g-1 (x) = ⅓ x + 1 ⅔

Answer 3

okay then what

Answer 4

that is the answer. g-1 (x) = ⅓ x + 1 ⅔

Answer 5

those arent the possible answers so thats incorrect

Answer 6

that is correct.

Answer 7

ill get someone to make sure . @mathmale am i right ?

Answer 8

is it possible that the mixed # should be a improper fraction ?

Answer 9

Plohrr: I'll be right with you; I'm going to check what you've done. Glad to hear from you.

Answer 10

Nice work, Plohrr! Would you please explain the steps of the process of finding the inverse of g(x) to peachesandcream? Thanks.

Answer 11

she said its incorrect !

Answer 12

It wouldn't matter if you ended up with an improper fraction.

There are various ways in which to write the inverse function. Personally, I'd write it

f^(-1) = (x+5)/3. But this is exactly equivalent to your result.

Answer 13

soo. maybe the choice is different in the book

Answer 14

I'd suggest you suggest the correct result is
-1 x + 5
f (x) = -----------
3

Do you, Plohrr, know how to check whether a function f(x) and its inverse f^(-1) actually are inverses? Hint: f^(-1) (f(x)) MUST EQUAL x.

Answer 15

I've checked it myself and find that our result absolutely is correct. Again, Plolrr, expressions such as this can be expressed in various ways. Again I assert that y our initial response was correct, just as mine is correct.
