QUESTION 2 2.1. \( \quad \) Solve for \( x \) 2.1.1. \( (x-2)(3 x+1)=0 \) 2.1.2. \( \left(\frac{1}{3}\right)^{3 x-1}=81 \)

Write the function whose graph is the graph of \( y=(x+4)^{2} \), but is reflected about the \( x \)-axis. \( y=\square \) (Simplify your answer.)

4. Jug A contains 5 times as much water as Jug B. After some water is poured from Jug A to Jug B, there are 1860 ml of water in each jug. How much water is poured from Jug A to Jug B?

If \( f(x)=\left\{\begin{array}{ll}2 x-5 & \text { if }-2 \leq x \leq 4 \\ x^{3}-4 & \text { if } 4<x \leq 5\end{array}\right. \), find: (a) \( f(0) \), (b) \( f(1),(c) f(4) \), and \( (d) f(5) \). (a) \( f(0)=\square \) (b) \( f(1)=\square \) (c) \( f(4)=\square \) (d) \( f(5)=\square \)

-11) \( \frac{22^{4} \cdot 8^{4}}{121^{4} \cdot 4^{6}}= \)

9. Use any method to solve the system: \( \left\{\begin{array}{c}x^{2}+y^{2}=9 \\ 9 x^{2}+4 y^{2}=36\end{array}\right. \)
