Question

then {f^2-f^2}÷ F. please answer​

Answer 1

Step-by-step explanation:

Differentiate 3f(x)−2f(x1)=x with respect to x,

3f′(x)−2f′(x1)(−x21)=1

3f′(x)+x22f′(x1)=1                       (1)

Put x=2 in equation (1),

3f′(2)+222f′(21)=1

3f′(2)+21f′(21)=1                         (2)

Put x=21 in equation (1),

3f′(21)+(

Answer 2

Step-by-step explanation:

3f(x) - 2f(x1) (-x21) = 1

3f(x) + x22f (x1) = 1

x=21
