limit as x approaches 3+of (3-x)/(x^2-9)

x \to 3 + lim (\frac{3 - x}{x ^{2} - 9})

- \frac{1}{6}

Decimal

- 0.16666 \dots

Solution steps

x \to 3 + lim (\frac{3 - x}{x ^{2} - 9})

Simplify

\frac{3 - x}{x ^{2} - 9} : - \frac{1}{x + 3}

= x \to 3 + lim (- \frac{1}{x + 3})

Plug in the value

x = 3

= - \frac{1}{3 + 3}

Simplify

= - \frac{1}{6}
