Answer and Explanation:

From the question, we're asked to explain how the graph of 7x^2 will be narrower than the graph of 1/7x^2.

To explain this, we have to note that how narrow a parabola will be is determined by how large the coefficient of x^2 is. So the greater the coefficient of x^2, the narrower the graph will be.

We can see that the coefficient of x^2 in 7x^2(which is 7) is greater than the coefficient of x^2 in 1/7x^2( which is 1/7), so the graph of 7x^2 will be narrower than the graph of 1/7x^2.
