Question

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.

f(x) = x2 - 3 and g(x) = √(3+x)

Answer 1

please help!!! 15 mins to complete the quiz!! 2nd to last question left!!

Answer 2

substitute g(x) for x in f(x)

f(x) = x2 - 3
f(g(x)) = ( sqrt 3+x)^2 - 3

f(g(x)) = 3+x-3

solve this u get ur answer

similar way u do it for g(f(x))

Answer 3

hmm.. so itd be = x+6? im terrible at math and dont understand this question at all

Answer 4

noo ...

first to find f(g(X) substitute g(x) in place of x

tell me what to do get???

Answer 5

hmmm..

Answer 6

idk i get comfused with the square root sign

Answer 7

ok




got it ???
