ADVANCED FUNCTIONS ASSIGNMENT

PLEASE HELP ASAP WITH MY ADVANCED FUNCTIONS ASSIGNMENT. I DID IT WRONG AND NEED FULL ANSWERS PLEASE FROM 5-7!!

5. Given f(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) a) (f+2)(x) b) (fog)(x) 6. Given f(x) – 2", g(x) = x3+ 1, h(x) – logzx, determine how they were combined to create the following graphs. Explain your reasoning. b) 7. Approximate the IROC for the following (three decimals as needed, radian mode). a) f(x) = – atx = 2 x-1 b) g(x) = sin(x) + 2 at x = 7/6
