**What does 'for all real values of x' mean? The Student Room**

All, all real, all real numbers. But what's the range? Maybe I'll do that in a different color just to highlight it. What is going to be the range here, what is the set of all possible outputs? Well if you think about, actually, to help us think about, let me actually draw a graph here. Of what this looks like. What this looks like. So the graph of "f(x) is equal to x squared" is going to look... Determine the domain of a function A function f is a rule that assigns to each element x in a set A (called the domain of f) exactly one element f(x) in a set B (called the range of f). If a function f is given by a formula and the domain is not speciﬁed, the convention is that the domain of the function is the set of all real numbers for which the formula makes sense and deﬁnes a real

**Quadratic Equations How do I find the values of real**

Therefore, the domain (the set of x-values) consists of all real numbers. However, the range (the set of y -values) is bounded by the y -value of the vertex. Example 8: Determine the domain and range: y = x 2 − 4 x …...The domain of f(x) = x 2 is all real numbers and the range is all nonnegative real numbers. The graph in the figure below suggests that the function has no absolute maximum value and has an absolute minimum of 0, which occurs at x = 0.

**Quadratic Equations How do I find the values of real**

If only the rule y = f(x) is given, then the domain is taken to be the set of all real x for which the function is deﬁned. For example, y = √ x has domain; all real x ≥ 0. This is sometimes referred to as the natural domain of the function. 1.1.4 Range of a function For a function f: X → Y the range of f is the set of y-values such that y = f(x) for some x in X. This corresponds to the how to end bullying in schools Determine the domain of a function A function f is a rule that assigns to each element x in a set A (called the domain of f) exactly one element f(x) in a set B (called the range of f). If a function f is given by a formula and the domain is not speciﬁed, the convention is that the domain of the function is the set of all real numbers for which the formula makes sense and deﬁnes a real.
