Answer:

Completing the table, we have;

Step-by-step explanation:

Given the equation;


y=2x-1

where y is the output and x is the input.

we were given the outputs 1,3,5.

To get the input for each of the given output let us substitute the output into the equation and solve for x;


\begin{gathered} \text{for output = 1;} \\ 1=2x-1 \\ 1+1=2x \\ 2=2x \\ x=(2)/(2) \\ x=1 \end{gathered}
\begin{gathered} \text{for output = 3 ;} \\ 3=2x-1 \\ 3+1=2x \\ 4=2x \\ (4)/(2)=x \\ x=2 \end{gathered}
\begin{gathered} \text{for output = 5;} \\ 5=2x-1 \\ 5+1=2x \\ 6=2x \\ (6)/(2)=x \\ x=3 \end{gathered}

Therefore, completing the table, we have;
