Answer:
(fog)(x) = 4x - 7
Step-by-step explanation:
f(x) = 2x-1 and g(x) = 2x-3;
(fog)(x) = f(g(x)
= f(2x - 3) = 2(2x - 3) - 1
= 4x - 6 - 1
= 4x - 7

Answer:
• mathematical: y ≤ 52
• reasonable: 0 ≤ y ≤ 52
Step-by-step explanation:
The reasonable range is the set of heights between the maximum height and the ground (y=0).
___
The maximum height is about 44.51 meters, so values between that and 52 meters are not in the reasonable range. A maximum height of 52 meters requires an initial velocity of about 15.4 m/s.
