Решите уравнение. f(x) = y, f(x) = 1 - x^4
( f ( - 2x ) - 1 )^2 = 256 ( 1 - 2 f ( x) + f^2 ( x ))
( f ( - 2x ) - 1 )^2 = 256 ( 1 - 2 f ( x) + f^2 ( x ))

Решите уравнение. f(x) = y, f(x) = 1 - x^4f(x) = y,???? вот это - не понятно что...
( f ( - 2x ) - 1 )^2 = 256 ( 1 - 2 f ( x) + f^2 ( x ))
f ( - 2x )= 1-(-2x)^4
(1-(-2x)^4 -1)^2=256(1-2( 1 - x^4 )+(1 - x^4 )^2)
(-16x⁴)²=256(1-x⁴-1)²
256x⁸=256x⁸
x- любое...
