Functions

1. 1. The domain of a function is the complete set of posible values of the independent variable, meanwhile the range is the complete set of resulting values of the independent variable once submitted to the function.

2. 2. A polynomial is an equation of two or more algebraic terms, specially the sum of lots of terms that have each different Powers. The power of a polinomial can be either a constant, positive whole numbers or

3. 4. The degree of a polynomial tells us the number of posible solutions the polynomial has when equalizing to zero (roots). With this we can determine the number of times the graph cuts the x-axis (degree of polynomial).

4. 5. The roots of a polynomial are all its posible solutions (where it cuts the x-axis).

5. 6. A relation is stablished when each product of set X has a result in set Y, the requirements for a relation to be posible are two, first each input (X) should have an output and second each input (x) must have only one output (y).
