TRANSCRIPT
• I can graph a radical function. • I can perform transformations on a radical function.
Lesson 4.8 ~ Graphing Radical Functions OBJECTIVES:
This should look very familiar! • A negative out front reflects over the x-axis. • A number out front stretches (if it’s >1) or compresses (if it’s <1) the graph. • A number directly attached to x within grouping symbols moves us to the left or right. • A number added or subtracted to the end of the equation moves us up or down.
This is a graph of our parent function. We will use transformations the same way we have in the past. 1. Move left or right
(horizontal translation). 2. Reflect over the x-axis and
stretch or compress. 3. Move up or down (vertical
translation).
The main points that we will move are (0, 0) and (1, 1).
