Vertical Stretches and Shrinks of Functions
The coefficient in the function affects the graph of by stretching or compressing it vertically. If , the graph is compressed vertically (appears "wider" for parabolas). If , the graph is stretched vertically (appears "skinnier" for parabolas). Key formulas include expressions such as a. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 1: Linear Functions.
Key Concepts
The coefficient $a$ in the function $f(x) = a \cdot g(x)$ affects the graph of $g(x)$ by stretching or compressing it vertically. If $0 < |a| < 1$, the graph is compressed vertically (appears "wider" for parabolas). If $|a| 1$, the graph is stretched vertically (appears "skinnier" for parabolas). If $a$ is negative, the graph is also reflected across the x axis.
