How do i use composition of functions to determine whether the functions in each pair are inverse functions?
y=2x-3 and y=2x+3
y=2x-3 and y=2x+3
1 Answer
f(g(x)) does not equal x, so the functions are not inverses.
Explanation:
This is how to figure this out:
Write
Determine:
So, since f(g(x)) doesn't equal x, the functions are not inverses!
Hope this helps!
