Connecting BIG ideas and Answering the Essential Questions

1 Equivalence
Radical expressions can be represented in many ways. To simplify a square root, factor out perfect squares from the radicand.
Simplifying Radicals (Lesson 10-2)
square root of 12 equals square root of 4 dot square root of 3 equals 2 square root of 3
Operations With Radical Expressions (Lesson 10-3)
square root of 5 dot square root of 10 equals square root of 50 equals 5 square root of 2
2 Functions
Square root functions contain a variable in the radicand. The parent square root function is y equals square root of x .
Graphing Square Root Functions (Lesson 10-5)
Graph of the parent square root function
A curve rises from approximately (0, 0) through approximately (1, 1) and (4, 2).
3 Solving Equations and Inequalities
To isolate the variable in a radical equation, first isolate the radical and then square both sides.
Solving Radical Equations (Lesson 10-4)
2 x equals . square root of 4 x plus 3 end root
