उत्तर

\[\lim_{x \to 0} \left[ \frac{3^{2 + x} - 9}{x} \right]\]
\[ = \lim_{x \to 0} \left[ \frac{3^2 \cdot 3^x - 3^2}{x} \right]\]
\[ = 3^2 \lim_{x \to 0} \left[ \frac{3^x - 1}{x} \right]\]
\[ = 9 \log \left( 3 \right)\]
\[ = 9 \log_e 3\]

Find `lim_(x -> 0)` f(x) and `lim_(x -> 1)` f(x) where f(x) = `{(2x + 3, x <= 0),(3(x+1), x > 0):}`


If the function f(x) satisfies `lim_(x -> 1) (f(x) - 2)/(x^2 - 1) = pi`, evaluate `lim_(x -> 1) f(x)`.
