We were doing review in class today and I remembered this one question I never got(though I don't have the specific question with me anymore).

Question

1. It was a composite function question that asked for 'a' when f(g(a))=1. We were provided with the graphs of f(x) and g(x) and there were no equations for either one of those two functions, and the two graphs were reciprocal functions with some type of transformation(really hard to decipher)

So how could I approach this question? Algebraically? We are allowed graphing calculators, but I don't know how to use one.

2. There was a graph with zeros of 5 and -1, and it asked least amount of units it needed to shift horizontally so both of the zeros are positive.

Is 0 a positive number? If so, then I could shift it 1 to the right and get 6 and 0 as the new x intercepts instead.
