Let the people initially on the train be 'x'.
19 people got off the train --> x - 19
17 people got on the train --> x - 19 + 17
Remaining people on the train = 63
Therefore, x - 19 + 17 = 63
x - 2 = 63
x = 63 + 2
x = 65
Verification:
65 - 19 + 17 = 63
65 - 2 = 63
63 = 63

Answer:
y = √(4x - 8) - 3
Step-by-step explanation:
y = 1/4(x + 3)² + 2
To find the inverse, switch the places of the x and y.
x = 1/4(y + 3)² + 2
Solve for y.
x - 2 = (1/4(y + 3)² + 2) - 2
x - 2 = 1/4(y + 3)²
4(x - 2) = 4(1/4(y + 3)²)
4x - 8 = (y + 3)²
√(4x - 8) = √((y + 3)²)
√(4x - 8) = y + 3
√(4x - 8) - 3 = (y + 3) - 3
√(4x - 8) - 3 = y
y = √(4x - 8) - 3
