Domain Examples In Math

The pioneer in work on the affective domain in mathematics was mcleod 1989b who referred to it as a broad range of feelings and moods which are generally considered to be different from pure cognition including as specific components attitudes beliefs and.

Domain examples in math. The domain of a linear function is all real numbers therefore domain. In the relation above the domain is 2 4 11 21 the range is is 5 31 11 3. It is the set of all values for which a function is mathematically defined.

Notice the lines and dots. Interval notation and set notation. An example in which the domain is not all real numbers is when a function results in an undefined number.

The function f x x2 has a domain of all real numbers x can be anything and a range that is greater than or equal to zero. When 1 is entered into the function the end result is 3 divided by 0 which is an undefined number. Find the domain of the function f x 2x 2 12x 5.

Find the domain of f x 5x 3. Relations are often represented using arrow charts connecting the domain and range elements. We will read this graph from left to right.

Domain of the relation 3 4 9 8 4 5 is 3 4 9. For the function f x 2x 1 what s the domain. F x x 2.

The figure above shows how we can use a number line to help us write the domain of a function in interval notation. It is quite common for the domain to be the set of all real numbers since many mathematical functions can accept any input. Find the domain and range of the function f x sqrt x 2 x 2 9 without using a graph.
