Tolong dibantu no 7 dan 8 dengan cara yang lengkap jelas dan jawaban yang benar JANGAN ASAL

NILAI MUTLAK

8][
f(x) = |2x - 1|
f(3) = |2•3 - 1| = |5| = 5

g(x) = |5 - x|
g(3) = |5 - 3| = |2| = 2

f(3) - g(3)
= 5 - 2
= 3 ← jwb


7][
f(x) = |x - 5|

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

f(0) + f(5) - f(10) × f(-2)
= 5 + 0 - 5 × 7
= 5 + 0 - 35
= - 30 ← jwb
