Determine h(x-1) for the following function

Question

h(x)=3x/x^2+6x+5

Answer 1

First, I suppose that the denominator is a quadratic expression, so IT SHOULD BE ENCLOSED IN PARENTHESES SO THAT THE PROPER ANSWER, USING PEMDAS, WILL ALWAYS OCCUR.

 

Now, to answer your question, wherever x appears in the definition of function h, replace it by (x-1).  You'll be expected to simplify that, of course
