Question: such the limx-0^+(T(x), x = 0) and T(x) is continuous at x=20000

why is it important for these 2 conditions to hold(state 2 reasons)

Suppose a state's income tax code states that tax liability is 12% on the first $20,000 of taxable earnings and 16% on the remainder. By hand, find constants a and b for the tax function T(x)= a +0.12x if x 20,000
