One of the most difficult concepts for students to understand is how to graph functions affected by horizontal stretches and shrinks. This depends on the direction you want to transoform. Parent Function: f (x) = 1 x f ( x) = 1 x Horizontal Shift: Left 4 4 Units Vertical Shift: Down 3 3 Units Reflection about the x-axis: None Here is a list of topics: F (x) functions and transformations. To zoom, use the zoom slider. y = 1/x (reciprocal) Also, when \(x\)starts very close to 0 (such as in in thelog function), we indicate that \(x\)is starting from the positive (right) side of 0 (and the \(y\)is going down); we indicate this by \(\displaystyle x\to {{0}^{+}}\text{, }\,y\to -\infty \). Every point on the graph is compressed \(a\) units horizontally. This would mean that our vertical stretch is 2. Instead of using valuable in-class time, teachers can assign these videos to be done outside of class. 2.3: Transformations of Functions - Mathematics LibreTexts *The Greatest Integer Function, sometimes called the Step Function, returns the greatest integer less than or equal to a number (think of rounding down to an integer). It usually doesnt matter if we make the \(x\) changes or the \(y\) changes first, but within the \(x\)s and \(y\)s, we need to perform the transformations in the order below. 1. g (x) = x 2-1 Parent: Transformations: 2. f (x) = 2|x-1 Parent: Transformations: For problem 1-9, please give the name of the parent function and describe the transformation represented.
