what is the order, from narrowest to widest graph, of the quadratic functions f(x) = -10x^2, f(x) = 2x^2, f(x) = 0.5x^2

Question

a. f(x) = -10x^2, f(x) = 2x^2, f(x) = 0.5x^2
b. f(x) = 2x^2, f(x) = -10x^2, f(x) = 0.5x^2
c. f(x) = 0.5x^2, f(x) = 2x^2, f(x) = -10x^2
d. f(x) = 0.5x^2, f(x) = -10x^2, f(x) = 2x^2

Answer 1

The order from narrowest to widest graph is:

c. f(x) = 0.5x^2, f(x) = 2x^2, f(x) = -10x^2
