limit as x approaches-4 of (3x+2)(x-2)

x \to - 4 lim ((3 x + 2) (x - 2))

60

Solution steps

x \to - 4 lim ((3 x + 2) (x - 2))

Plug in the value

x = - 4

= (3 (- 4) + 2) (- 4 - 2)

Simplify

(3 (- 4) + 2) (- 4 - 2) : 60

= 60

x \to 4 lim (2 x^{2} + 4 x + 1)

x \to 0 lim (ln (1 - e^{x}))

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

x \to 2 lim (4 x - 3)

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