Find the definition field (1) y = loga (X & # 178; + 1) (a > 0 and a ≠ 1) (2) loga absolute value (x-1) + loga (x + 1) (a > 0 and a ≠ 1) (1) Y = loga (X & # 178; + 1) (a > 0 and a ≠ 1) (2) Absolute value of loga (x-1) + loga (x + 1) (a > 0 and a ≠ 1) (3) F (x) = 1 / radical (1-x) + LG (3 + x)

Find the definition field (1) y = loga (X & # 178; + 1) (a > 0 and a ≠ 1) (2) loga absolute value (x-1) + loga (x + 1) (a > 0 and a ≠ 1) (1) Y = loga (X & # 178; + 1) (a > 0 and a ≠ 1) (2) Absolute value of loga (x-1) + loga (x + 1) (a > 0 and a ≠ 1) (3) F (x) = 1 / radical (1-x) + LG (3 + x)

1 x & # 178; + 1 > 0 is always true, so x is all real numbers
2 1 absolute value (x-1) > 0 and 2 (x + 1) > 0, so x of solution 1 is not equal to 1, and solution 2 obtains x > - 1 to take union set x > - 1 and X is not equal to 1
