limit as x approaches 5 of x^2-2x-3

x \to 5 lim (x^{2} - 2 x - 3)

12

Solution steps

x \to 5 lim (x^{2} - 2 x - 3)

Plug in the value

x = 5

= 5^{2} - 2 \cdot 5 - 3

Simplify

= 12

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

x \to - \frac{1}{3} lim (\frac{6 x ^{3}}{2})

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

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

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