Answer:
Step-by-step explanation:
if you use a graphing calculator you we see that the smaller the leading coeffient the wider the parabola.
or use a table and plug in values for y for each x
y = x² 5x² 15x²
x = 1 1 5 15
x = 2 4 20 60
y is larger for a larger ax² a coeffient
so the is more narrow for a higher coeffient
f(x) = 5x² has the smallest coeffient so the widest parabola
