limit as x approaches 2 of x^3+2x^2-x-4

x \to 2 lim (x^{3} + 2 x^{2} - x - 4)

10

Solution steps

x \to 2 lim (x^{3} + 2 x^{2} - x - 4)

Plug in the value

x = 2

= 2^{3} + 2 \cdot 2^{2} - 2 - 4

Simplify

2^{3} + 2 \cdot 2^{2} - 2 - 4 : 10

= 10

\frac{d}{d x} ((3 x^{2} + 5) (3 x - 1)^{2})

2 x^{2} e^{x}

f (x) = \frac{3}{4 x ^{5}}

\frac{d}{d x} (4 x^{8} + 3 e^{7 x})
