Looking at the graph, we can see that g(x) intersects f(x) at two points - one point where g(x) is above f(x) and one point where g(x) is below f(x). The smaller solution to g(x) = f(x) would be the value of x where g(x) is below f(x. In the given graph, this occurs at x = 6. Therefore, the correct answer is b. 6.
