Answer:
They are inverse functions
Step-by-step explanation:
A property of inverse functions is that if
We can plug in x = 3
That means that, supposing they are inverse functions, g(7) should equal 3
It checks out
Another way to see if two functions are inverse is to swap the x and y of one of the functions.
ex.
Since, after the swap, the functions are equal, we know it is an inverse function
