    • 9.1: The Square Root Function
      In this section we turn our attention to the square root function, the function defined by the equation f(x)=√x. We begin the section by drawing the graph of the function, then we address the domain and range. After that, we’ll investigate a number of different transformations of the function.
    • 9.2: Multiplication Properties of Radicals
      n this section we introduce the concept of simple radical form.
    • 9.3: Division Properties of Radicals
    • 9.4: Radical Expressions
      In this section, we will simplify a number of more extensive expressions containing square roots, particularly those that are fundamental to your work in future mathematics courses.
    • 9.5: Radical Equations
      In this section we are going to solve equations that contain one or more radical expressions.
    • 9.6: The Pythagorean Theorem
      Pythagoras was a Greek mathematician and philosopher, born on the island of Samos (ca. 582 BC). He founded a number of schools, one in particular in a town in southern Italy called Crotone, whose members eventually became known as the Pythagoreans. Today, nothing is known of Pythagoras’s writings, perhaps due to the secrecy and silence of the Pythagorean society. However, one of the most famous theorems in all of mathematics does bear his name, the Pythagorean Theorem.
