The graphs of the functions f(x) = log 12x, g(x) = log 4, and (f - g)(x) = log 12x - log 4 are shown. Explain why the graph of g(x) extends to the negative side of the y-axis, but the graph of (f - g)(x) does not. Also, conjecture about another function equivalent to (f - g)(x) that has only 1 term on the right side of the equation instead of 2. Explain your reasoning. 2 f(x) V - 8 (x) 1 g(x) -5 4 -3 -2 -1 1 2 3 4 -1
