A kangaroo leaps a total distance of 3 feet with a maximum height of 1 foot. Another kangaroo is originally 5 feet in front of the first kangaroo and jumps the same distance, but 6 inches higher. Write the equation representing the path of each kangaroo. A. Kangaroo 1: y=-(x-3)^2+1 ; kangaroo 2: y=-(x-5)^2+1.5
B. Kangaroo 1: y=-(x-1.5)^2+1 ; kangaroo 2: y=-(x-6.5)^2+1.5
C. Kangaroo 1: y=-4/9(x-3)^2+1 ; kangaroo 2: y=-2/3(x-5)^2+1.5
D. Kangaroo 1: y=-4/9(x-1.5)^2+1 ; kangaroo 2: y=-2/3(x-6.5)^2+1.5
