Domain of x

• Is the domain the X or y value?

  The domain and range of a function is all the possible values of the independent variable, x, for which y is defined. The range of a function is all the possible values of the dependent variable y.

• Is the domain the X or the Y axis?

  Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

• Is the domain the x coordinate?

  Domain The set of all the values which may be input into a function. That is, the set of all the values the independent variable may assume. Graphically, the domain is the set of all the x-coordinates. Range The set of all the values which are output when the function is evaluated at all the input values from the domain.

Let’s examine the graph of the function to determine the range: f(x) 6 3x 6 3x 0 6 3x 0 3x 6 x 2 x 2 The domain is represented by the x-values: Left to Right on the graph since the x-axis runs left to right. This graph keeps moving outward in both directions: D =

  Solution: Since the denominator isx2−x=x(x−1), which would become zero whenx= 0or whenx= 1, and since divided by zero is not allowed, the numbers 0 and 1 cannot be inthe domain of f. On the other hand, for any value of xother than 0 and 1, the fomular off(x) defines a real number. Thus the domain of fis all the real numbers except 0 and 1.

  To find the domain for a graph with two endpoints, always identify the x-values of the point farthest to the left and the point farthest to the right. For the range, you want the y-values of the lowest point and the highest point. Domain: {-7 ≤ x < 5}

  There are two main ways to write domains: interval notationandset notation.Interval notation used parenthesis or brackets to imply where the function is de ned. In thecase of our example, we would write our domain using interval notation in the following way: : (1;0)[(0;1) (2)

To do this we will solve. x2+2x¡3 = 0: After solving this, we will exclude its solu- tions from the domain. x2+2x¡3 = 0 (x+3)(x¡1) = 0.
