Question

inverse or not? check my answer please??

Answer 1

I got -x and -x for the answers. Does this mean they are inverses of each other??

Answer 2

they would be inverses of each other only if
f(g(x)) and g(f(x)) would be +x only
not when -x

Answer 3

is the rule if you end up with the same answers then it is inverse?

Answer 4

Ohhh okay thank you. my teacher said that but I didnt know if it was also for -x

Answer 5

only for +x
both must be +x , nothing else
welcome ^_^

Answer 6

so if another function pair was -4 , -4 or -4 , +4 It is still not an inverse correct?

Answer 7

the function would be constant to get f(g) or g(f) = constant.
and yes,anything apart from +x , not inverse

Answer 8

okay thanks
