\[ y = \frac{1}{4} \cdot 8 = 2 \]
\[ y = \frac{1}{4} \cdot \frac{1}{2} = \frac{1}{8} \]
\[ y = \frac{1}{4} \cdot (-4) = -1 \]
\[ y = \frac{1}{4} \cdot (-3) = -\frac{3}{4} = -0.75 \]
\[ -\frac{1}{4} = \frac{1}{4}x \]
\[ x = -1 \]
\[ 0 = \frac{1}{4}x \]
\[ x = 0 \]
\[ 16 = \frac{1}{4}x \]
\[ x = 16 \cdot 4 = 64 \]
\[ 0.3 = \frac{1}{4}x \]
\[ x = 0.3 \cdot 4 = 1.2 \]
Ответ: 1) y(8) = 2; y(1/2) = 1/8; y(-4) = -1; y(-3) = -0.75; 2) x(-1/4) = -1; x(0) = 0; x(16) = 64; x(0.3) = 1.2
