tolong dijawab ya .? soal nya bsok di kumpul

Ini jawaban dari soal limit

3.
[tex] \lim_{x \to 1} \frac{(x^2-1)}{(x-1)} [/tex]
[tex] =\lim_{x \to 1} \frac{(x+1)(x-1)}{(x-1)} [/tex]
[tex] =\lim_{x \to 1} (x+1) [/tex]
= 1+1
= 2 (b)

4.
[tex] \lim_{x \to 3} \frac{x^2-x-6}{(x-3)} [/tex]
[tex]= \lim_{x \to 3} \frac{(x+2)(x-3)}{(x-3)} [/tex]
[tex]= \lim_{x \to 3} (x+2)[/tex]
= 3+2
= 5 (c)

5.
[tex] \lim_{x \to 0} \frac{x^2+10x}{x^3+2x} [/tex]
[tex] =\frac{0^2+10}{0^3+2} [/tex]
= 10/2
= 5 (d)
