The minimum value of (x + 1) ² - 6 is (), and the power of x = ()

The minimum value of (x + 1) ² - 6 is (), and the power of x = ()

The minimum value of (x + 1) ² - 6 is (- 6), and the power of x = (- 1)
Analysis: (x + 1) ² > = 0, so (x + 1) ² - 6 > = - 6, if and only if (x + 1) = 0, the equal sign holds, when x = - 1,
(x + 1) & # - 6 get the minimum value - 6, (- 1) ^ 2009 = - 1
