limit as x approaches 2 of (x+1)(3x^2-9)

x \to 2 lim ((x + 1) (3 x^{2} - 9))

9

Solution steps

x \to 2 lim ((x + 1) (3 x^{2} - 9))

Plug in the value

x = 2

= (2 + 1) (3 \cdot 2^{2} - 9)

Simplify

(2 + 1) (3 \cdot 2^{2} - 9) : 9

= 9

2 x^{2} + 5, [- 2, 3]

x \to 1 lim (\frac{∣ 1 - x ∣}{1 - x})

y^{^{''}} + y = 7 sin (x)

\frac{d}{d x} (ln (x^{8} y))

\int_{0}^{1} x e^{5 x} d x
