Best ResponseYou've already chosen the best response.1Hint: dw:1433363568951:dw Here you have a=100, b=1.07 just need a few more points to give the shape of the graph.

Best ResponseYou've already chosen the best response.1The graph that I drew freehand is sufficient for most purposes. Some teachers require at least one more point so that the graph defines completely the function.

Best ResponseYou've already chosen the best response.1Looked at it again, the graph is actually \(y=100(1.7^x)\), my bad! Except for b=1.7 (and not 1.07), the graph holds. Typically in a graph of an exponential function \(f(x)=a(b^x)\) f(0)=a, (because x=0, f(0)=\(ab^0=a, because b^0=1\) This point was indicated on the graph. f(1)=ab (because x=1, f(1)=\(ab^1=ab\)

Best ResponseYou've already chosen the best response.1Yes, one more point like f(1)=170 defines the function completely, since a and b will then be defined.
