Figure 1 shows a sketch of the curve with equation y=f(x)y = f(x)y=f(x). The curve passes through the origin O O\,O and through the point (6,0)(6, 0)(6,0). The maximum point on the curve is (3,5)(3, 5)(3,5).
On a separate diagram, sketch the curve with equation y=3f(x)y = 3f(x)y=3f(x). Show clearly the coordinates of the maximum point and of each point at which the curve crosses the xxx-axis.
On a separate diagram, sketch the curve with equation y=f(x+2)y = f(x + 2)y=f(x+2). Show clearly the coordinates of the maximum point and of each point at which the curve crosses the xxx-axis.
