limit as x approaches-4 of x^2-3x+12

x \to - 4 lim (x^{2} - 3 x + 12)

40

Solution steps

x \to - 4 lim (x^{2} - 3 x + 12)

Plug in the value

x = - 4

= (- 4)^{2} - 3 (- 4) + 12

Simplify

(- 4)^{2} - 3 (- 4) + 12 : 40

= 40

x \to 4 lim (6 x + 5)

x \to \infty lim (27)

x \to \infty lim (22)

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

x \to a lim (\frac{- 3}{0})
