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

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

- 25

Solution steps

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

Plug in the value

x = - 3

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

Simplify

(- 3)^{3} - 3 (- 3) - 7 : - 25

= - 25

x \to 0 lim (\frac{e ^{x^{2}} - cos ( x )}{sin ^{2} ( x ) + 3 sin ^{5} ( x )})

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

x \to - 1 + lim (2 x + 1)

x \to 0 + lim ((1 + 5 x)^{\frac{2}{x}})

x \to 0 lim (sin (\frac{1}{x}) x^{2})
