Answer:
Latihan1
1. F(x)=
𝑥+2
𝑥−5
a. X=3,001
maka f(x)=
3,001+2
3,001−5
=
5,001
−1,999
= -2,5017
b. X=2,99
maka f(x)=
2,99+2
2,99−5
=
4,99
−2,01
=-2,482
Observation It appears that when x is close to 3 in value, then f(x) is close to
-2 in value.

2. F(=x)=
𝑥−5
4𝑥
a. x=1,002
maka f(x)=
1,002−5
4(1,002)
=-
−3,998
4,008
=0,9975
b. 0,993
maka f(x)=
0,993−5
4(0,993)
=
−4,007
3,972
=1,008
Observation: It appears that when x is close to 1 in value, then f(x) is close to
1 in value.
3. f(x)=
3𝑥2
𝑥
a. x=.0,001
maka f(x)=
3(0.001)
2
0,001
=
0,000003
0,001
=0.0015
b. x= -0,001
maka f(x)=
3(−0,001)
2
−0,001
=
0,000003
−0,001
=-0,0015
observation:It appears that when x is close to 0 in value, f(x) is not close to
any fixed number in value.
