    Hint: Cross Multiply to get G(5) = 1(2)

    And then convert the fraction that you get into a decimal.

    So we have G/2=1/5. What we can do here is to cross-multiply 2 to both sides like hero said. |dw:1345218960338:dw| Now we have G=2/5 which is 0.4, answer B. to convert a fraction to a decimal just divide 2 into 5 and you'll get 0.4 if you didn't know that :) -Hope it helps :)

    g%28x%29=x-2 To find the composite f(g(x)), substitute (x-2) where there is an x in f(x). f%28g%28x%29%29=%28-2%29%2F%28%28x-2%29%2B5%29-1 f%28g%28x%29%29=%28-2%29%2F%28x%2B3%29-1 The domain of f(g(x)) is all points except x=-3, since the denominator goes to zero. For the range of f(x), as x gets large, either positive or negative, the term (-2)/(x+3) goes to zero and f%28x%29-%3E-1 Here is the graph of f(g(x)). +graph%28+300%2C+300%2C+-20%2C+20%2C+-5%2C+5%2C%28-2%29%2F%28x%2B3%29-1%29+ That was f(g(x)). Now for the inverse. To find the inverse of y=%28-2%29%2F%28x%2B3%29-1 Reverse x and y and solve for y.
