4. My mother is tred. 5. My father is striet. 6. My aunt is shy.

Write the domain in interval notation. (a) \( f(a)=6-|a-3| \) (b) \( g(a)=\frac{3}{6-|a-3|} \) (c) \( h(a)=\frac{3}{6+|a-3|} \)

ACROSS B \( 18.25 \times 20.2 \) F \( 945.12 \div 6.6 \) H \( 90.8-19.7 \) \( 2.2 \times 1.2 \) K \( 9.75 \div 1.2 \) M \( 2.41+3.3-8.9 \)

Jika \( f(x)=\cos x \cdot \sin 2 x \) maka \( f^{\prime}\left(\frac{\pi}{4}\right)=\ldots \)

Collect like terms. \( 9 u^{3} v-8 u v^{8}+9 u^{3} v-3 u v^{8} \) The answer is
