Question 2

$\begin{gathered} c)\text{ output = (input}*\text{ input) }+\text{ 1} \\ d)\text{ output = input + 5} \end{gathered}$

Step-by-step explanation:

$\begin{gathered} c)\text{ Change in input = 4 - 3 , 3 - 2, 2 -1 } \\ \text{change in input = 1 (it is constant )} \\ \text{The output depends on the input.} \end{gathered}$
$\begin{gathered} To\text{ get output 2: (1 }*1\text{ )+ 1 = 1 +1 = 2} \\ To\text{ get output 5: (2}*2)\text{ + 1 = 4 + 1 = 5} \\ To\text{ get output 10: (3}*3)\text{ + 1 = 9 + 1 = 10} \\ To\text{ get output 17: (4}*4)\text{ + 1 = 16 + 1 = 17} \\ To\text{ get output 26: (5}*5)\text{ + 1 = 25 + 1 = 26} \end{gathered}$
$\begin{gathered} \text{Formula for the Process = (input}*\text{ input) }+\text{ 1} \\ Process=(input)^2\text{ }+\text{ 1} \\ \text{output = (input}*\text{ input) }+\text{ 1} \end{gathered}$

$\begin{gathered} d)\text{ rate of change = }\frac{change\text{ in output }}{\text{change in input}} \\ \text{rate of change = }(-5-(-15))/(0-(-2))\text{ = }(10-(-5))/(3-0)\text{ = }(15-10)/(4-3) \\ \text{rate of change = }(10)/(2)\text{ = }(15)/(3)=(5)/(1) \\ \text{rate of change = 5} \end{gathered}$
$\text{output = input + 5}$
