y is greater than 0 x exist in a set of real numbers
A positive real number is any natural, integer, rational, or irrational number x such that x>0. In other words, the real numbers indicated by with or without positive sign (+) is known as Positive Real Number. Positive Real numbers are indicated by R+ mathematically.For example R+ = {1, 2, 3, 4, 5, .....}
the range is a positive real number
The range of y = nx consists of all positive real numbers, and the domain consists of all real numbers.
The absolute value of a number is positive, so the range is always a positive real number. You are correct. The domain, that is the value before you take the absolute value, is all real numbers, but the range is always positive.
If what you mean is F(x) = 63x then the range is all real numbers.
domain is set of real numbers range is set of real numbers

The range of y=2x is All Real Numbers
domain: all real numbers range: {5}
The Domain and Range are both the set of real numbers.
If the domain is the real numbers then so is the range.

It depends on the domain but, if the domain is the real numbers, so is the range.
The function y=x is a straight line. The range is all real numbers.
