/ 3 \ x \x - 3/*e
d // 3 \ x\ --\\x - 3/*e / dx
Apply the product rule:
f(x)=x3−3f{\left(x \right)} = x^{3} - 3f(x)=x3−3; to find ddxf(x)\frac{d}{d x} f{\left(x \right)}dxdf(x):
Differentiate x3−3x^{3} - 3x3−3 term by term:
Apply the power rule: x3x^{3}x3 goes to 3x23 x^{2}3x2
The derivative of the constant (−1)3\left(-1\right) 3(−1)3 is zero.
The result is: 3x23 x^{2}3x2
g(x)=exg{\left(x \right)} = e^{x}g(x)=ex; to find ddxg(x)\frac{d}{d x} g{\left(x \right)}dxdg(x):
The derivative of exe^{x}ex is itself.
The result is: 3x2ex+(x3−3)ex3 x^{2} e^{x} + \left(x^{3} - 3\right) e^{x}3x2ex+(x3−3)ex
Now simplify:
The answer is:
/ 3 \ x 2 x \x - 3/*e + 3*x *e
/ 3 2\ x \-3 + x + 6*x + 6*x /*e
/ 3 2 \ x \3 + x + 9*x + 18*x/*e
