\( f(x)=\left\{\begin{array}{lll}-(x+1)^{2}+1 & \text { for } & x<2 \\ x-1 & \text { for } & x \geq 5\end{array}\right. \) Find \( f(-1) \)

1. One number is four times another. Their sum is 35 . Find the numbers.

3. The greater of two numbers is one less than 8 times the smaller. Their sum is 98 . Find the numbers.

14. \( 4^{x}=4096 \)

Part A A tie-dye kit with one T-shirt costs \( \$ 15 \). Each additional T-shirt costs \( \$ 4 \) more. Choose the explicit formula to represent the situation. A. \( a_{n}=11+4 n \) B. \( a_{n}=4+15 n \) Cl. \( a_{n}=19+4 n \) Kids

Part B A tie-dye kit with one T-shirt costs \( \$ 15 \). Each additional T-shirt costs \( \$ 4 \) more. Choose the recursive formula to represent the situation. \( \begin{array}{ll}\text { A. } a_{n}=a_{n-1}+4 ; a_{1}=11 \\ \text { B. } a_{n}=a_{n-1}+4 ; a_{1}=15 \\ \text { C. } a_{n}=a_{n-1}+11 ; a_{1}=15 \\ \text { D. } a_{n}=a_{n-1}+19 ; a_{1}=11\end{array} \)
