The graph of a quadratic parent function $f\left(x\right)=x^2$ is transformed to create the graph of g(x)=7f(x). Which statement best describes g(x)?

The graph of g(x) goes up 7 units from the graph of f(x)

The graph of g(x) goes down 7 units from the graph of f(x)

The graph of g(x) is narrower than the graph of f(x)
