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

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

7

Solution steps

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

Plug in the value

x = - 2

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

Simplify

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

= 7

x \to 2 lim (5 x + 6)

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

x \to 0 - lim (x + \frac{4}{x ^{2}})

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

x \to a lim (f (x) g (x))
