(d^2)/(dx^2)(3+5x+2x^2+0.4x^3)

\frac{d ^{2}}{d x ^{2}} (3 + 5 x + 2 x^{2} + 0.4 x^{3})

2.4 x + 4

Solution steps

\frac{d ^{2}}{d x ^{2}} (3 + 5 x + 2 x^{2} + 0.4 x^{3})

\frac{d}{d x} (3 + 5 x + 2 x^{2} + 0.4 x^{3}) = 1.2 x^{2} + 4 x + 5

= \frac{d}{d x} (1.2 x^{2} + 4 x + 5)

\frac{d}{d x} (1.2 x^{2} + 4 x + 5) = 2.4 x + 4

= 2.4 x + 4
