If the point P (1 + 2a, 4-2a) is symmetric about the origin and the point is in the third quadrant, then the integer solution of a
∵ the point P (1 + 2a, 4 + 2a) is symmetrical about the origin, so the point P is in the first quadrant
∴1+2a>0①4-2a>0②,
From (1), a > negative half,
From ②, a < 2,
A = 1 or 0
Let f (x) be an odd function with period 3 defined on R and f (1) = - 1, then f (11) =?
f(11) = f(4*3 -1) = f(-1) = -f(1) = 1
If the function y = 4x − 2 is a decreasing function in the interval [3,6], then the minimum value of Y is ()
