Examine the graph that represents this situation. What are the domain and range of the part of the function that represents this situation?  The domain is \( x > 0 \) , and the range is \( y > 0 \) . \( 0 < x \leq 17,0 < y \leq 16 \). The domain is \( 0 < x \leq 17 \), and the range is\( 0 < y \leq 16 \) . The domain is \( 0 < x < 17 \) , and the range is \( 0 < y < 16 \) . The domain is \( x \geq 0 \) , and the range is \( y \geq 0 \) . 

\( \left. \begin{array} { l } { 14 . f ( x ) = - 2 x ^ { 2 } + 4 x + 3 } \\ { x } \\ \hline - 2 \\ { - 1 } \\ { - 1 } \\ { 0 } \\ { 1 } \\ { 2 } \end{array} \right. | \)

9. An ice manufacturing machine requires 10 minutes to warm up before the production of ice begins. The weight, in tonnes, of ice produced varies directly as the number of hours of production. Given that 20 tonnes of ice are produced when the machine is run for half an hour, find the weight of ice manufactured when the machine is run for \( 1 \frac{3}{4} \) hours.

Solve the equation \( x: \log _{x+1}\left(x^{2}+x-6\right)^{2}=4 \) We have

Solve the equation: \( \sqrt{x + 4} = 6 \)
