Step-by-step explanation:
Since f is a linear function then its graph must be a line
to draw a line ,all you need is plotting two points.
f(0)=1/2(0)+2=0+2=2 then the line passes through the point (0,2)
f(2)=1/2(2)+2=1+2=3 then the line passes through the point (2,3)
look ok at the photo below for the graph.
