Question 370462: Please help me finish solving this verification! I need to verify that two functions are inverses. They are: f(x)=(-4/7)x-(16/7) and g(x)= (3/2)x-(3/2)
I got this far, and if I am wrong please correct me
f(g(x)= (-4/7)*(((3/2)x)-(3/2))-(16/7)
please help!!

You can put this solution on YOUR website!
f(x)=-4x/7 - 16/7
y=-4x/7 - 16/7
x=-4y/7 - 16/7
4y/7= -x - 16/7
4y/7= -x - 16/7
y=-7x/4 - 4
f^-1(x)=-7x/4 - 4 The inverse of f(x)
.
Are you trying to do a f(g(x)) rather than an inverse? They are not the same.
