I'm having trouble with this, it's the first time we cover Difference Quotients and I don't know how to solve them as a fraction. Thanks for your help!
g(x) = 1/(x+2)
Do you mean without actually doing anything yourself? I can't think of any way- my experience is that no matter how long I stare at the paper, nothing appears on it. Normally, what I would have to do is write out the formula for a "difference quotient", the put the specific function I am interested into the formula in the right places. After that it is just 'algebra', perhaps things like subtracting fractions by getting the same denominator.
