Examples of set of real numbers?
Some examples of sets of real numbers include: The set of positive integers: {1, 2, 3, 4, ...} The set of rational numbers: {1/2, -3/4, 5/6, ...} The set of whole numbers: {..., -2, -1, 0, 1, 2, ...} The set of natural numbers: {0, 1, 2, 3, 4, ...} The set of irrational numbers: {√2, π, e, ...}
Are -1 and 1 real numbers?
Yes, -1 and 1 are real numbers. Real numbers consist of irrational numbers, rational numbers and integers.
Is there a real zero between -1 and -2?
1
What two numbers have a sum of 2 and a product of 2?
There are no real numbers that will satisfy the requirements. In the complex field, the solution is 1+i and 1-i where i is the imaginary square root of (-1); that is, i^2 = -1
The meaning of range in algebra term?
Given a function f(x), the domain is all of the numbers you are allowed to put in it (in other words x), and the range is all of the numbers you can get from it (in other words f(x)).Here are a few examples:f(x) = 3x+2D: All real numbers (-inf,inf)R: All real numbers (-inf,inf)f(x) = |x| + 2 (where |x| is the absolute value of x)D: All real numbers (-inf,inf)R: All real numbers greater than or equal to 2 [2,inf)f(x) = 1/(4x^2-1)D: All real numbers except 1/2 and -1/2 (because if you plug in either of those you get 1/0 which is undefined) (-inf,-1/2) u (-1/2,1/2) u (1/2,inf)R: All real numbers greater than or equal to -1 except 0. [-1,0) u (0,inf)

What is a number real?
a number that cant be written on a number line. (ex. √-1) (the check is a square root sign)
1/2 belongs to what family of real numbers?
Rational
Identify the difference between natural number and real number?
The set of natural numbers or counting numbers N is a subset of the set of real numbers R. N = {1, 2, 3, ...) R = {..., -2, -1, -0.5, 0, 1, √2, 2, 3, π, ...}

What two numbers multiply together to equal 2 and add to be -2?
0
What adds to negative 1 and mulitplies to positive 2?
There are no real numbers that can do that.The two numbers that can are- 1/2 - 1/2 j sqrt(7)and - 1/2 + 1/2 j sqrt(7)

If the sum of 2 numbers is 4 and the product of these numbers is 13 what are these 2 numbers?
The question has no answer in real numbers. The solution, in complex numbers, are 2+3i and 2-3i where i is the imaginary square root of -1.
