PLEASE HELP REALLY BADLY. FAN + MEDALL

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

f(x)= x-7/x+3 g(x)= -3x-7/ x-1

@loreinaramos113 do you know how to do this

anonymous · Answer

hold up let me see

anonymous · Answer

I know you plug in g(x) everytime there is an x in the f(x) equation, but its confusing since its a fraction.

this is about tangets and graphs, I just want to know how to show its inverse, Do i plug in g(x) to f(X)

anonymous · Answer

yes

Find the domain of the given function.

f(x) = square root of x+3 / (x+8) (x-2)

 x > 0
 All real numbers
 x ≥ -3, x ≠ 2
 x ≠ -8, x ≠ -3, x ≠ 2
is the answer C

no
