Di ketahui fungsi f(x)= |x-4| tentukan nilai dari f(0)+f(4)-f(8)×f(-2)=
Jawab:
-20
Penjelasan dengan langkah-langkah:
f(x) = |x-4|
f(0) = |0 – 4| = |-4| = 4
f(4) = |4 – 4| = |0| = 0
f(8) = |8 – 4| = |4| = 4
f(-2) = |-2 – 4| = |-6| = 6
Jadi :
f(0) + f(4) – f(8) × f(-2)
4 + 0 – 4 × 6
4 + 0 – 24
4 – 24
