limit as x approaches-2 of x^2-5

Solution

x \to - 2 lim (x^{2} - 5)

Solution

- 1

Solution steps

x \to - 2 lim (x^{2} - 5)

Plug in the value

x = - 2

= (- 2)^{2} - 5

Simplify

(- 2)^{2} - 5 : - 1

= - 1

Popular Examples

integral from 1 to infinity of x^{-4/5}

\int_{1}^{\infty} x^{- \frac{4}{5}} d x

f^{^{'}} (x) = 6 x

derivative of f(x)= 2/(3x)derivative of

f (x) = \frac{2}{3 x}

derivative of (3x^2/(x^2-4))
