Interactive Graph: Horizontal Stretching and Compression

Explore how changing the value of \(k\) affects the graph of the function \(f(x) = \vert{}k \cdot x\vert{}\). Adjust the slider below to apply horizontal compression (\(\vert{}k\vert{} > 1\)) or horizontal stretching (\(0 < \vert{}k\vert{} < 1\)).
