Answer:
Step-by-step explanation:
(3,1) lies below the vertex, so the parabola opens downwards.
Equation for a down-opening parabola with vertex (2,3):
y = a(x-2)² + 3, a<0
Plug in (3,1) and solve for a:
1 = a1² + 3
a = -2
y = -2(x-2)² + 3
12 is B. You because the graphs slope is 1. 13 is A 7 I think.
25/20 × 100% = 125%
125% - 100% = 25%
25% profit :)
