PreCalculus 12 3. a) Graph the exponential function > = [ ;) b) Determine: i) whether the function is increasing or decreasing ii) the intercepts iii) the equation of the asymptote iv) the domain of the function v) the range of the function (4.) Sierpinski's triangle is formed in this way. Figure 0 Figure 1 Figure 2 Each time, one-quarter of the shaded area is removed. Assume Figure 0 has area 80 m. a) Determine a function that models the shaded area, A square metres, of Figure n. b) Determine which figure has a shaded area of approximately 1 1 m
