Answer:
y(0) = 3
Explanation:
This is solved by plugging in each option one by one, and seeing which one results in a positive value for dy/dt.
dy/dt = (4 − 1) (1 − 2²) = -9
dy/dt = (7 − 1) (1 − 1²) = 0
dy/dt = (1 − 1) (1 − 2²) = 0
dy/dt = (-4 − 1) (1 − 0²) = -5
dy/dt = (3 − 1) (1 − 0²) = 2
Only the last option fits.
