Hey there! Just doing some review problems, i got a good amount of the math done but i'm having trouble in a few spots. If you could answer both questions and just list the steps out that would be awesome thanks!

A cost function is given by C(q) = 92 + 29 (a) Find the intervals where the cost function is increasing /decreasing (Hint: After you take the derivative, you should try to factor the numerator before solving this problem) (b) Find the intervals where the average cost is increasing/ decreasing. (The hint in part (a) applies here as well. You might at some point need to use the quadratic formula 4. Let f and g be differentiable functions satisfying f (1) = 3, f'(1) = 4, g(1) - -2 and g' (1) = 2. Let h(x) = f(x)/g(x). Find the equation of the line tangent to y = h(x) at T =1
