What are some examples of rational numbers and integers?

First, a integer is a whole number positive or negative.

For example: 2,5,7,2000000,10,400,-10,-400,2848993

These are all integers.

A rational number is a real number that can be described by a integer:

2, 57 6747374

These are all rational numbers.

Extra:

A irrational number is a real number that can’t be described with a integer.

For example,

Square root of 3. Square root of 5 etc

Hope this helped

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
