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

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

23

Solution steps

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

Plug in the value

x = - 2

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

Simplify

3 (- 2)^{2} - 2 (- 2) + 7 : 23

= 23

x \to 0 lim (\frac{1}{2.5})

x \to \frac{π}{2} lim (sin (2 x + π))

x \to 0 lim (csc (x) - tan (x))

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

x \to 4 lim (\frac{x ^{2} - 6}{x + 2})
