5. Given R(x) - log(x) and g(x) = cos(x), sketch these graphs. Explain your reasoning and be clear about domains. (Tip: If stuck, try subbing in some x-values) b) (fog)(x ) 6. Given f(x) = 2*, g(x) = x2+ 1, h(x) = log2x, determine how they were combined to create the following graphs. Explain your reasoning. a) b ) h(f(x>). Acomposition of two inverse functions will create a straight line like we see here. the h is onthe Outside because log functions cannot go into the negatives so the i 7. Approximate the IROC for the following (three decimals as needed, radian mode).Side a) f(x) = - atx = 2 b) g(x) = sin(x) + 2 at x = 1/6
