Which of the quadratic functions has the narrowest graph? y = -x^2 or y = 1/6x^2 or y = 2x^2 or y = 1/8x^2
Answer:
The equation with the highest leading coefficient (the number before the x^2 term) will have the narrowest graph. Here, we have to choose between -1, 1/6, 2, and 1/8. The highest number out of all of those numbers is 2, so y = 2x^2 will have the narrowest graph.
