For which function is f(x) equal to f-1(x)? a. f(x)=x+6/x-6 b. f(x)=x+2/x-2 c. f(x)=x+1/x-1 d. f(x)=x+5/x-5

A reflection in the x-axis means the y-coordinate will be negated (the opposite sign). This means that g(x)=-f(x)=-(x^2+5=-x^2-5.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

it's both, now can you answer my most recent question?
