Here we explain about the aspacts of a function, which is called one to one mapping. Overall, a function has one to one mapping if for every value of x there is one and only one value of y. For example, 2y + 3x = 6 is a function. A function has many to one mapping if more than one values of x equal to the same value of y. For example, y = f(x) = x^{2}. The mini-lesson will also show you the graphical representation and tabular representation of one to one mapping and many to one mapping with the help of examples.

Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.

For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship.?

Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).
