You can put this solution on YOUR website!
f%28x%29=1%2Fx+ and g%28x%29=1-2x, find the value of f%28g%28-3%29%29


First, find the inner value g%28-3%29


g%28-3%29+=+1-2x


g%28-3%29+=1-2%28-3%29


g%28-3%29+=1%2B6


g%28-3%29+=+7


--------------------------------------------


Now take that result and plug it into f(x):


+f%28x%29+=+1%2Fx


+f%28g%28-3%29%29=+f%287%29+=+1%2F7


So the answer is +f%28g%28-3%29%29+=1%2F7
