Radical Functions

Learning Objectives

• Write the domain of  functions involving a radical expression.

• Graph radical functions and transformations of these.

• Restrict the domain of a quadratic function to obtain a related one-to-one function, and then compute the inverse of this.

• Use the radical conjugate to rationalize the numerator or denominator of a given expression and simplify the result.

• Compute the average rate of change of a radical function.

• Solve equations involving radical expressions.
