Write an equation that represents the following transformation. f(x)=|x| ; vertical stretch by a factor of 3 followed by a translation 7 units down.

Pls help asap

For example, if a function increases three times as fast as its parent function, it has a stretch factor of 3. To find the vertical stretch of a graph, create a function based on its transformation from the parent function, plug in an (x, y) pair from the graph and solve for the value A of the stretch

i hope this is what you were looking for.
