    \[y_{1}=\frac{1}{x},\ y_{2}=\frac{5}{x+6}\]Can you visualize y1 or y2? If so, draw a sketch of the graph(s)

    It might help to think of y2 as\[y_{2}=5(\frac{1}{x+6})\]

    is the second one y = (5/x) +6 or y = (5) / (x+6) ?

    I think you have the graphs for y = 1/x and y = (5/x) +6 not (5) / (x +6)

    it does both are same things but the one graph is a little wide near the origin and u get y=5 for x=1

    u see the magniture of the function increased with multiplying by 5 and graph shifted to the left with the 6

    For an equation to compare them... lets call them f1(x) and f2(x) \[f _{1}(x) = y _{1} =\frac{ 1 }{ x }\]\[ f_{2}(x) = y _{2} =\frac{ 5 }{ x+6 } = 5\left( \frac{ 1 }{ x+6 } \right)\]

    \[f _{2}(x) =5 \times f _{1}(x+6)\]
