limit as x approaches-1 of 5x^3-x^2+3x+7

x \to - 1 lim (5 x^{3} - x^{2} + 3 x + 7)

- 2

Solution steps

x \to - 1 lim (5 x^{3} - x^{2} + 3 x + 7)

Plug in the value

x = - 1

= 5 (- 1)^{3} - (- 1)^{2} + 3 (- 1) + 7

Simplify

5 (- 1)^{3} - (- 1)^{2} + 3 (- 1) + 7 : - 2

= - 2

x \to 0 lim (\frac{5 sin ( 3 x )}{x})

x \to π lim (π cos (x))

x \to - 1 lim (3 π)

n \to \infty lim (n - 3 n^{2})

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