2 answers:
Answer:
The set of numbers of the form , q≠0 and q≠ 1 or -1.
Step-by-step explanation:
We have that,
U = the universal set = the set of all rational numbers
S = set of all integers.
It is required to find .
Now, is the complement of the set S.
i.e. = U - S = set if rational numbers - set of integers
i.e. = the set of rationals which are not integers i.e. the set of points of the form
, q≠0 and q≠ 1 or -1.

What it means is, check the picture below.
so, the first part shows two rectangles... the rectangle goes from 1.0 to 1.6, so it has a width of 0.6.
and the height comes from the middle point, or 1.3 is f(1.3) = (1.3)² or 1.69.
so you get the area of the first rectangle, 0.6 * 1.69
and then you do the same for the second rectangle, it goes from 1.6 to 2.0, so is of width 0.4, and its height comes from the middle 1.8 point, is f(1.8) = (1.8)², or 3.24.
so its area is 0.6 * 3.24
then you add the areas of the rectangles to approximate the area under the parabola.
so, you'd do the same for the other part of the picture with the four rectangles.
the first rectangle of the four for example, has a width of 0.2 and a height of f(1.1) = (1.1)² or 1.21.
