limit as x approaches-2 of sqrt(x^2-4)

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

0

Solution steps

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

Plug in the value

x = - 2

= (- 2)^{2} - 4

Simplify

(- 2)^{2} - 4 : 0

= 0

d er i v a t i v e f (x) = x^{\frac{4}{3}}

\int_{2 π}^{\infty} sin (x) d x

\int sin (\frac{π}{4} x) d x

d er i v a t i v e sin (x y^{2})

x \to - 3 lim (\frac{x ^{3} + 27}{x ^{2} + 13 x + 30})
