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

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

- 4

Solution steps

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

Plug in the value

x = - 1

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

Simplify

3 (- 1)^{2} + 2 (- 1) - 5 : - 4

= - 4

x \to 1 lim (∣ (3 - 4 x) ∣)

x \to - \frac{π}{2} lim (- 4 x - \frac{π}{2})

x \to 0 + lim (\frac{1 + ln ( x )}{x})

x \to \infty lim (x^{2} - 5 x)

x \to 5 lim (2 x - 1)
