It is known that f (x) is an odd function on R. when x is greater than or equal to 0, f (x) = 2 to the power of X + 2x + B, then f (- 1) is an important process
F (x) is an odd function on R
When x is greater than or equal to 0, f (x) = 2
Because, x0
So, f (- x) = 2 to the - x power - 2x + B
Because f (x) is an odd function on R, f (- x) = - f (x)
So, X
