is the parent graph like this: $y = \left| x \right|$

2. Michele_Laino

if yes, we can write this: $f\left( x \right) = \left| x \right|$ and: $g\left( x \right) = 3\left| x \right| = 3f\left( x \right)$ so at a generic point $$x$$ graph of $$g(x)$$ is stretched by a factor $$3$$ with respect to the graph of $$f(x)$$

3. Michele_Laino

more precisely, I mean vertically stretched
