Question
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 iis taxable income in dollars.
t(i) =
0.12i
655+0.13(i-14000)
4500+ b(i-40000)
if 0 ≤ i ≤ 15,000
if 15,000<i≤ 37,000
if i > 37,000
Part A: Show that the function t(i) is not continuous at /= 15,000.
Part B: Find the value of constant b that makes (1) continuous at /= 37,000.
