Пошаговое объяснение:

1 . a ) f(g(x)) = √( 3 - 4x) ; b ) f(g(x)) = 3 - 4√x ; c ) f(g(x)) =2 / ( x²+ 4 ) ; d ) f(g(x)) =(2/x)² + 4.

2 . a ) f(x) = 1/x ; g(x) = √(5 - 2x ) ;

b ) f(x) = x⁴ ; g(x) = x² + 5x - 1 ;

c ) f(x) = 10/x³ ; g(x) = 3x - x² .

3 . a ) y = 6( 5 - x )³ ; y' = 6 * 3( 5 - x )² * ( 5 - x )' = - 18 ( 5 - x )² ;

b ) y = √( 3x - x²) ; y' = 1 /2√( 3x - x²) * ( 3x - x²)' = ( 3 - 2x )/2√( 3x - x²) ;

c ) y = 4 /( 5x - 2 )² ; y' = 4 * ( - 2 )(5x - 2 )⁻³ *( 5x - 2 )' = - 40/( 5x - 2 )³ .
