limit as x approaches 1 of 2x^3-4x^2+x+9

x \to 1 lim (2 x^{3} - 4 x^{2} + x + 9)

8

Solution steps

x \to 1 lim (2 x^{3} - 4 x^{2} + x + 9)

Plug in the value

x = 1

= 2 \cdot 1^{3} - 4 \cdot 1^{2} + 1 + 9

Simplify

= 8

5 x^{2} + x - 5, at x = 8

n = 1 \sum \infty \frac{\frac{l n ( n + 4 )}{n ^{\frac{5}{2}}}}{\frac{1}{n ^{\frac{5}{2}}}}

\frac{\partial}{\partial x} (ln (\frac{x y}{z}))

\int (e^{2 x} + e^{- 2 x})^{2} d x

x \to 0 lim (arccos (x^{2}))
