1.1 Find the domain of the following functions of: g(x) = (x - 1)(2 – 2). 1.2 The size of an insect population at time t (measured in days) is given by p(t) = 3000 - 2000 2009. Determine the initial population P(0) and the population size after 4 days 1.3 In a test for blood sugar metabolism, conducted over a time interval, the amount of sugar in the blood was a function of a time t (measured in hours) and given by: A(t) = 3.9 +0.2t – 0.1t2, find the amount of sugar in the blood a. at the beginning of test, b. 3 hours after the beginning. 1.4 Sugar costs 50 cents per kilogram for the amount up to 10kg and 40cents per kilogram for the amount in excess of 10kg. If c(x) denotes by means of algebraic formulas. 1.5 Sketch the graph of the set of inequalities: x +y > 2 and 3x + y< 3. 1.6 Given f(x) = r2 and g(x) = V2-1 a. (fog)(). b. (gof)(3) a.
