(4*e^(-6*x))'The calculation above is a derivative of the function f (x)
(4)'*e^(-6*x)+4*(e^(-6*x))'
0*e^(-6*x)+4*(e^(-6*x))'
0*e^(-6*x)+4*e^(-6*x)*((-6*x)'*ln(e)+(-6*x*(e)')/e)
0*e^(-6*x)+4*e^(-6*x)*((-6*x)'*ln(e)+(-6*x*0)/e)
0*e^(-6*x)+4*e^(-6*x)*(((-6)'*x-6*(x)')*ln(e)+(-6*x*0)/e)
0*e^(-6*x)+4*e^(-6*x)*((0*x-6*(x)')*ln(e)+(-6*x*0)/e)
0*e^(-6*x)+4*e^(-6*x)*((0*x-6*1)*ln(e)+(-6*x*0)/e)
0*e^(-6*x)+4*e^(-6*x)*((-6*x*0)/e-6*ln(e))
0*e^(-6*x)+4*e^((-6)'*x-6*(x)')
0*e^(-6*x)+4*e^(0*x-6*(x)')
0*e^(-6*x)+4*e^(0*x-6*1)
0*e^(-6*x)+4*0^(-6*x)
0*e^(-6*x)+4*-6*e^(-6*x)
-24*e^(-6*x)
