Hi, I just need help with a couple of questions from my Calculus homework, appreciate the help. Take your time, thank you

1. Canadian federal income tax mks on a graduated system, meaning the amount that you pay depends on your income. Within each tax bracket, you only pay the income tax rate on the amount of your income that falls within that range. For example, if you earn $50,000, then you pay 15% on the first $48,535 and 20.5% on the remaining $1,465. The 2020 Canadian federal income tax rates are shown below: I 2020 Federal Income Tax Bracket I 2020 Federal Income Tax Rate I $48,535 or less 15% more than $48,535 and up to $97,059 more than $97,069 and up to $150,473 more than $150,473 and up to $214,368 M than $214,358 Table 1: Canadian federal tax rates Let T(:r) represent the amount of income tax (in dollars) that a Canadian person paid in 2020 based on their income, :7: (in dollars). (3) Based on the information in the table, T(a:) is a piecewise defined function of the form: 0.15:7: if a: S 48, 535 0.205(5; 48535) + 7230.25 if 48, 535 a+ 3. The left and right limits are not equal. 11:2 + 82': + 1 the + Now for fun, try to graph an). 2 2 - 225 (1 point) Choose the best reason that the function f (a) = is discontinuous at a = -15. Ex + 15 A. lime-a f(x) + f(a) B. limr-+a f(a) doesn't exist. C. The function is not defined at a. Answer:(1 point) Suppose 0f(x)gm2+4m+4 Use this to compute the following limit. 11m f(-'B) :z>2 Answer: What theorem did you use to arrive at your answer? Answer: (1 point) Find a value of the oonstant k, if possible, at which _ R2322 a25 f($)_{4m+k m>5 is continuous everywhere. k 2 (enter "none" if no value). (1 point) Find the limit. Notes: Enter "DNE" if limit Does Not Exist. rm :32 + sin(;c) = 33-0 :1
