Question

What is the order, from narrowest to widest graph, of the quadratic functions f(x) = –10x², f(x) = 2x², f(x) = 0.5x²
a. f(x) = –10x², f(x) = 2x², f(x) = 0.5x²
b. f(x) = 2x², f(x) = –10x², f(x) = 0.5x²
c. f(x) = 0.5x², f(x) = 2x², f(x) = –10x²
d. f(x) = 0.5x², f(x) = –10x², f(x) = 2x²

Answer 1

The bigger the coefficient (in absolute value) the taller the graph is at any particular value of x. So, go from the largest (in absolute value) coefficient to the smallest.
