1. Solve the following tasks:
1.23 At what slope the sides of an isosceles trapezoid area it would be greatest if the sides are equal b, a smaller base and.

2. Carry out a full investigation of these functions and build their schedules.
2.23 y = (x3 + 4) / x2

3. Carry out a full investigation of these functions and build their schedules.
3.23 y = x - ln (1 + x2)

4. Find the minimum and maximum values of the function y = f (x) on the interval [a; b]
4.23 y = e6x - x2, [-3; 3]
