Piecewise Linear Functions

Which of the following linear piecewise functions are graphed above?

Choose one answer

f(x)=\begin{cases} 3x-1&0\le{x}\le{3}\\ \frac{7}{3}x+1&3<x<6\\ -15x+9&6\le{x}\le{10} \end{cases}

f(x)=\begin{cases} x-1&0\le{x}\le{3}\\ -\frac{1}{3}x+1&3<x<6\\ -x+9&6\le{x}\le{10} \end{cases}

f(x)=\begin{cases} x-1&0\le{x}\le{3}\\ \frac{1}{3}x+1&3<x<6\\ -x+9&6\le{x}\le{10} \end{cases}

f(x)=\begin{cases} x+1&0\le{x}\le{3}\\ \frac{1}{3}x-1&3<x<6\\ x-9&6\le{x}\le{10} \end{cases}
