Answer 1

To determine the formula for the illustrated "T - chart"

Hence the formula for the T - chart = f(x) = 2x-7

Check

`\begin{gathered} \text{when x= 1} \\ f(x)\text{ = 2x-7} \\ f(x)\text{ = 2(1)-7} \\ f(x)\text{ = 2-7} \\ f(x)=-5 \\ \text{when x = 2} \\ f(x)\text{ = 2x-7} \\ f(x)\text{ = 2(2)-7} \\ f(x)=4-7 \\ f(x)=-3 \end{gathered}`

Therefore Option B is the correct answer
