limit as x approaches 1 of 3x^3-5x^2+x+8

x \to 1 lim (3 x^{3} - 5 x^{2} + x + 8)

7

Solution steps

x \to 1 lim (3 x^{3} - 5 x^{2} + x + 8)

Plug in the value

x = 1

= 3 \cdot 1^{3} - 5 \cdot 1^{2} + 1 + 8

Simplify

= 7

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

n = 1 \sum \infty (\frac{1}{2})^{- n}

4 t^{2} - 5 sin (3 t)

f (x) = - 3 x^{3} - 2 x^{2} - 1, at x = - 1

\frac{\partial}{\partial x} (\frac{x z}{x ^{2} + y ^{2}})
