1) Checking both functions, we can see that f(x) is stretched, and g(x) is compressed. Since 0vertically compressed and a>1 vertical stretch.
Let's check the graph of both transformed quadratic functions:
2) Now, let's check out the options: as we can see the graph of f(x)=5x²is narrower than g(x)=1/5x². So the answer is B (the second one).
