The amount of income tax, t, an individual owes is defined by piecewise function t(i) and is based on the individual's income, where i is taxable income in dollars. 0.10/ t(i)= 755+0.12(i-11000) 4500+ b(i-35000) if Osis 12,000 if 12,000 32,000 Part A: Show that the function t(i) is not continuous at i = 12,000. (10 points) Part B: Find the value of constant b that makes t(i) continuous at i = 32,000. (20 points)
