THIS USER ASKED 👇
f f (x) = 5 x minus 25 and g (x) = one-fifth x + 5, which expression could be used to verify g(x) is the inverse of f(x)?
THIS IS THE BEST ANSWER 👇
We study if the composition of the two functions equals the recognition (“x”), that is
Step by step explanation:
The composition of both functions should give an ‘x “if the other is inverse. That is, we need to find out what rendering. Note also that the same verification could be done with examination .
We work with :
So we see that the composition of both functions actually gives an “x”, and in that way we have verified that one is the inverse of the other.
