limit as x approaches 4-of 3/(x^2-16)

x \to 4 - lim (\frac{3}{x ^{2} - 16})

- \infty

Solution steps

x \to 4 - lim (\frac{3}{x ^{2} - 16})

For

x

approaching

4

from the left

, x < 4 \Rightarrow x^{2} - 16 < 0

The denominator is a negative quantity approaching 0 from the left

= - \infty

y = tan (2) (x)

3 arcsin (x^{4})

\frac{d}{d x} (- 131072 sin (2 x))

x \to (- 1^{+}) lim (4 x^{3} - 2 m)

ln (3 x^{3} + 2)
