A solar oven uses a parabolic reflector. The profile of the reflector is shown in the graph. What equation represents the axis of symmetry of the parabola? A) y = 0 B) x = 0 C) x = 0.3 D) y = 0.3

Without multiplying, tell which product is larger and why. 5 × 1/3 or 5 × 2/3 a)5 × 1/3 because 1/3 is less than 2/3 b) 5 × 1/3 because 1/3 is greater than 2/3 c) 5 × 2/3 because 1/3 is less than 23 d) 5 × 23 because 1/3 is greater than 2/3
