Use the definition of the derivative to determine all possoble values of A and B?(adsbygoogle = window.adsbygoogle || []).push({});

Use the definition of the derivative to determine all possoble values of A and B that make the function f differentiable at 0.

F(x)={ Ax^2 + Bx if -infin < x <= 0

{ x^3/2*cos(1/x) if 0<x<infin

I used defintion of derivative and equated both sides after i got both derivatives but i cant solve for the constants

any help
