What kind of transformation converts the graph of f(x)=|x|–1 into the graph of g(x)=8|x|–8?

Question

The answer options are...

horizontal shrink

horizontal stretch

vertical stretch

vertical shrink

Its asking which one of these transformations above makes the first equation convert into the second one.

Answer 1

It looks like to get from f(x) to g(x) you multiply by 8. Multiplying by 8 would be a vertical stretch.
