Question

8.

Which of the quadratic functions has the narrowest graph?


A. y = 1/9x2

B. y = –x2

C. y = 1/4x2

D. y = 4x2

Answer 1

D: y = 4x^2

Explanation:

The graph for which the absolute value of the coefficient of x is largest has the narrowest graph. That takes us immediately to D: y = 4x^2.
