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

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

2

Solution steps

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

Plug in the value

x = 1

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

Simplify

= 2

f (x) =, \frac{1}{x}

f (x) = - 3 tan (x) - e^{- x}

y^{^{''}} - 3 y^{^{'}} = (3 t + 8) sin (3 t)

\frac{d}{d x} (\frac{e ^{4 x}}{x ^{2}})

\int_{- 2}^{- 1} \frac{1}{x ^{3}} d x
