Maka,
a. f(−1) =
b. f(0) =
c. f(2) =
d. f(4) =
e. f(7) =​

Answer 1

Jawab:

Penjelasan dengan langkah-langkah:

Misalkan f(x) = |x/5|.

a. f(-1) = |(-1)/5| = |-1/5| = 1/5

b. f(0) = |(0)/5| = |0| = 0

c. f(2) = |(2)/5| = |2/5| = 2/5

d. f(4) = |(4)/5| = |4/5| = 4/5

e. f(7) = |(7)/5| = |7/5| = 7/5

Jadi, nilai-nilai f(x) untuk setiap x yang diberikan adalah:

a. f(-1) = 1/5

b. f(0) = 0

c. f(2) = 2/5

d. f(4) = 4/5

e. f(7) = 7/5
