Answer:
x = - , x = - 1
Step-by-step explanation:
Given
(x + 1)(3x + 4) = 0
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
3x + 4 = 0 ⇒ 3x = - 4 ⇒ x = -
Solutions from least to greatest are
x = - , x = - 1
1. First calculate the positive root of the quadratic using your preferred formula. I got a solution . That gives you the distance the ball traveled from d=0 (small hill). So the answer is A.
2. The domain is [0,2.121...]. The range is from 0 to the max height. The d for which the ball is the highest is given by the formula x = -b / 2a = -3.3/(-3.2) = 1.031... so the max is 1.902... So the range is [0,1.902...] So the answer is C.
