Suppose that the relation \( H \) is defined as follows. \( H = \{ ( 0,8 ) , ( 3 , n ) , ( 8 , p ) , ( 3 , q ) \} \) Give the domain and range of \( H \) . Write your answers using set notation. 

\( \left. \begin{array} { l } { x ^ { 2 } - x - 6 } \\ { x ^ { 2 } - x - 72 } \\ { x ^ { 2 } + 5 x - 6 } \\ { x ^ { 2 } - 4 x - 45 } \\ { x ^ { 2 } + 3 x - 18 } \end{array} \right. \)

4. The factors of \( 2 x^{2}-8 \) are: \( 2\left(4 x^{2}\right) \) \( 2\left(x^{2}+4\right) \)

Find the square. Simplify your answer. \( (3 y+3)^{2} \)

La ecuación de la linea recta asociada con la desigualdad \( 3 / 2 y-5 / 2 x \geq-2 \mathrm{es} \) : a. \( \quad y=\frac{5}{3}-\frac{4}{3} x \) b. \( \quad y=-\frac{5}{3} x+\frac{4}{3} \) c. \( y=\frac{5}{3} x-\frac{4}{3} \) d. \( y=-\frac{5}{3}+\frac{4}{3} x \)

\( \left. \begin{array} { l l } { x ^ { 2 } - 4 } & { = y ^ { 2 } - 2 ^ { 2 } } \\ { y ^ { 2 } - 1 } & { = } \\ { 25 x ^ { 2 } - 36 } & { = } \\ { 16 - 81 a ^ { 2 } } & { = } \end{array} \right. \)
