Now weve seen what it.

. Similar to how raw materials are used to manufacture specific products in a factory in a function the input values get processed in the function rule to deliver the output values. The raw materials required for the process can be identified as the domain of a function and the final products are the range. In geometrical terms the square root function maps the area of a square to its side length.

The principal square root function usually just referred to as the square root function is a function that maps the set of nonnegative real numbers onto itself. Finding the Domain and Range of a Function. For a function to be concave the slope of the function must be decreasing.

The square root of x is rational if and only if x is a rational number that can be represented as a ratio of two perfect squares. Go to Radical Expressions Functions Ch 10. Radical Expressions Functions.
