dik f (x) |x-5| tentukan nilai f(0) + f (5) -f (10) × f (-2)

NIlai mutlak

f(x)= |x - 5|

f(0) = |0-5|= 5
f(5) = |5-5| = 0
f(10)=|10-5|= 5
f(-2)=|-2-5|  = 7

f(0) + f(5) - f(10) x f(-2) =
= 5 + 0  - (5)(7)
= 5 - 35
= - 30

Materi harga mutlak

f(x) = |x-5|
f(0) = |0-5| = |-5| = 5
f(5) = |5-5| = 0
f(10) = |10-5| = 5
f(-2) = |-2-5| = |-7| = 7
sehingga
f(0) + f(5) - f(10) x f(-2) = 5 + 0 - 5 x 7 = 5 - 35 = -30
