limit as x approaches-2 of (1/2)^x

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

4

Solution steps

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

Plug in the value

x = - 2

= (\frac{1}{2})^{- 2}

Simplify

(\frac{1}{2})^{- 2} : 4

= 4

h \to 0 lim (h - 2)

h \to 0 lim (\frac{1 + h - 1}{h})

x \to 0 lim (\frac{x}{x ^{3} - 1})

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

x \to 5 lim (10 + ∣ x - 5 ∣)
