Given that the function f (x) is the domain of definition loga (x + 1) (a > 0, a ≠ 1), the maximum value in the interval [1,7] is 1 / 2 larger than the minimum value, the value of a is obtained

Given that the function f (x) is the domain of definition loga (x + 1) (a > 0, a ≠ 1), the maximum value in the interval [1,7] is 1 / 2 larger than the minimum value, the value of a is obtained

A = 1 / 16 or a = 16
