Question

If time is the input, what is the equation that represents this relationship?

Answer 1

two points of the graph of this relationship are: (0,1) and (2,4), therefore we have to calculate the slope

`m=(4-1)/(2-0)=(3)/(2)`

Having the slope we can find the equation

`\begin{gathered} y-1=(3)/(2)(x-0)=(3)/(2)x \\ y=(3)/(2)x+1 \end{gathered}`
