Square Root of a Function • [2.2] PRE-CALCULUS 12

The concept of the 'square root of a function' is introduced using a few simple examples. A function f(x) is compared to sqrt[f(x)] graphically, numerically, and algebraically.

My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.

Corresponds to chapter 2, section 2.2 in McGraw-Hill's Pre-Calculus 12, but also fits with the radical functions unit from almost any other Pre-Calculus course or textbook.
