1. Solve the following tasks:
1.29 page book printed text covers an area S; the width of the top and bottom margins equal to a, and the right and left - b. At what ratio of width to height of the text area of the entire page will be lower?

2. Carry out a full investigation of these functions and build their schedules.
2.29 y = (4 - 2x) / (1 - x2)

3. Carry out a full investigation of these functions and build their schedules.
3.29 y = e1 / (2-x)

4. Find the minimum and maximum values of the function y = f (x) on the interval [a; b]
4.29 y = 108x - x4, [-1; 4]
