How to Scale a Function Horizontally?
Horizontal scaling stretches or compresses a graph along the x-axis. Replacing x with bx in y = f(x) compresses the graph by a factor of b when b is greater than 1, and stretches it when b is between 0 and 1, the opposite of what most students expect. Below: the rule and worked examples.
How to Scale a Function Vertically?
Vertical Scaling, Example 1: Vertically stretch the function (y=(x+2)) by a factor of two. Exercises for Vertical Scaling Vertically stretch the function (f(x)=x^3) by a factor of (-frac{1}{3}). Vertically stretch the function (f(x)=sin x) by a factor of (3). Vertically stretch the function (f(x)=x^3) by a factor of (-frac{1}{3}). Vertically stretch the function (f(x)=sin x) […]
