Functions shown in different ways
Functions can be represented in various ways, such as algebraic expressions, tables, graphs, and verbal descriptions. Each representation provides different insights into the behavior and properties of the function.
Algebraic expression: Functions can be represented using mathematical equations that define the relationship between the input (independent variable) and the output (dependent variable). For example, the function f(x) = 2x + 3 represents a linear function that doubles the input value and adds 3.
Tables: Functions can also be displayed in tabular form, where the input values and corresponding output values are listed. Each input-output pair represents a point on the graph of the function. For example, the function f(x) = x^2 can be represented in a table as:
x | f(x)
0 | 0
