Hitunglah nilai limit fungsi berikut
Jawaban:
[tex] \frac{10}{11} [/tex]
[tex] \frac{ - 7}{12} [/tex]
Penjelasan dengan langkah-langkah:
c.
[tex]lim \: \frac{ {x}^{2} + 4x - 21 }{2 {x}^{2} - x - 15 } \: \: \: \\ lim \: \frac{(x + 7)(x - 3)}{(2x + 5)(x - 3)} \\ lim \: \frac{(x + 7)}{(2x + 5)} \\ lim \: \frac{3 + 7}{2(3) + 5} = \frac{10}{11} [/tex]
d.
[tex]lim \: \frac{6 - \sqrt{7x + 1} }{x - 5} \times \frac{6 + \sqrt{7x + 1} }{6 + \sqrt{7x + 1} } \\ lim \: \frac{36 - 7x - 1}{(x - 5)(6 + \sqrt{7x + 1} } \\ lim \: \frac{ - 7(x - 5)}{(x - 5)(6 + \sqrt{7x + 1)} } \\ \frac{ - 7}{6 + \sqrt{7(5) + 1} } \\ \frac{ - 7}{12} [/tex]
