Figure 1 shows a sketch of the curve with equation y=f(x)y = f(x)y=f(x). The curve passes through the point (0,7)(0, 7)(0,7) and has a minimum point at (7,0)(7, 0)(7,0).
On a separate diagram, sketch the curve with equation y=f(x)+3y = f(x) + 3y=f(x)+3.
On a separate diagram, sketch the curve with equation y=f(2x)y = f(2x)y=f(2x).
