Please answer questions below. I am a first year university student so keep the answers at that level

Question 1 (8 points) Non-linear (in)equations Determine the domain of denition then solve the foliowing: 3 a) 2\"\"1 = 4' '2 (4 points) b) Ln (x2 2x 3) > 0 (4 points) Question 2 (5 points) Compounding and investments in the period immediately following its initial public offering (IPO), OHaganBookseom's shares Were doubling in value every 3 hours. If you bought $10,000 worth of the stock when it was rst offered, how much were your shares worth after 8 hours? I Question 3 (12 points) Quadratic model A team of researchers was asked to study the extent of broadband access in Canada. It found some very old data online on broadband access from the start of 2001 to the end of 2003 and used it to construct the following quadratic model of the growth rate of broadband access: n(t) = 2:2 6t+12 (l is time in years; I = 0 represents the start of the year 2000) (1) Determine the appropriate domain of the function n (3 points) b) According to the model, when was the growth rate at a minimum?(3 points) c) Does the model predict a zero growth rate at any particular time? If so, when? (3 points) (I) What feature of this quadratic model indicates that the growth rate eventually increases? (3 points)
