Which of the quadratic functions has the narrowest graph?
Y = 1/3x^2
y = -3x^2
y = 1/8x^2
y = -2x^2
The quadratic function with the narrowest graph is y = -3x^2.
To compare the widths of quadratic functions, we look at the coefficient of x^2. The larger the coefficient, the narrower the graph.
In this case, y = -3x^2 has the largest coefficient (-3), making the graph narrower compared to the other options.
