Tolong dibantu no 4 yang a dan b dengan cara yang lengkap jelas dan jawaban yang benar .JANGAN ASAL!

Fungsi Harga Mutlak

f(x) = | 10 - 2x |
g(x) = | 2x + 6 |

(a) siapkan
f(-4) = | 10 - 2(-4) | = 18
g(-4) = | 2(-4) + 6 | = 2
f(10) = | 10 - 2(10) | = 10
[f(-4) x g(-4)] - [f(10)]²
= [18 x 2] - (10)²
= 36 - 100
= - 64

(b) siapkan
g(10) = | 2(10) + 6 | = 26
f(-5) = | 10 - 2(-5) | = 20
f(-2) = | 10 - 2(-2) | = 14
g(-2) = | 2(-2) + 6 | = 2
g(10) - f(-5) + [ f(-2) x g(-2) ]
= 26 - 20 + [14 x 2]
= 6 + 28
= 34
