The range of the function y = 3x + 1 for the domain 2 ≤ x ≤ 67 is given by the values of y when x varies from 2 to 67.
The minimum value of y is obtained when x = 2:
y = 3(2) + 1 = 7
The maximum value of y is obtained when x = 67:
y = 3(67) + 1 = 202
Therefore, the range of the function y = 3x + 1 for the domain 2 ≤ x ≤ 67 is 7 ≤ y ≤ 202.
The other ranges given (6 ≤ y ≤ 18, sy≤2, 7 ≤ y ≤ 19, 1, 5, sys 3) are not valid ranges for the function y = 3x + 1.
