Tugas Kalkulus pertemuan 13 - Aljabar Hitung Limit
8. Lim (x2 -20)
x→5
jawab: x2 -20
= 1(5)2 – 20
= 25 – 20
= 5
9. Lim (x2 + 3x + 1)
x→-2
jawab: x2 + 3x + 1
= 1(-2)2 + 3(-2) + 1
= 4 – 6 + 1
= -1
10. lim x + 2 / x - 3 = 0 + 2 / 0 - 3
x→0 = - 2/ 3
jawab: x + 2 / x - 3
= 0 + 2 / 0 - 3
= - 2/ 3
11. lim x2 + 2x - 8 / x2 - 4
x→2
jawab: x2 + 2x - 8 / x2 - 4
lim x2 + 2x – 8 / x2 -x -2 = (x+4) (x-2) / (x+ 1) ( x-2)
x→2 = ( x + 4) / (x + 1)
= 2 + 4 / 2 + 1
= 6 / 3
= 2
17. lim x2 – 4 / 3 - √x2 + 5
x→2
jawab: lim x2 – 4 / 3 - √x2 + 5 =3 + √x2 + 5 / 3 + √x2 + 5
x→2
lim (x2 – 4)(3 + √x2 + 5) / 9 – (x2 + 5)2 = lim (x2 – 4)(3 + √x2 + 5) / 4 - x2
lim – (3 + √x2 + 5) = - (3 + √x2 + 5) = - (3 + 3) = -6
