1.
The above figure shows a sketch of the curve with equation y=x(x-2)(x+3) . The graph crosses the x-axis at the points
(0,0) , (2,0) and (-3,0). In separate diagrams, sketch the curves with the following equations. On each diagram show
clearly the coordinates of each point at which the curve crosses the x-axis.
a) y=f(2x)
b) y=f(x-3)
c) y=f(-x)
d) y=-f(x)

The above figure shows a sketch of the curve with equation y=f(x). The graph has a maximum
point B(-1,0), a minimum point A(1,-4), x-intercept +2 and y-intercept -2. In separate diagrams,
sketch the curves with the following equations, showing clearly the coordinates of each point at
which the curve crosses the x-axis and the coordinates of both vertices (max and min).
a) Write down the equation of this curve.
Sketch
b) y=f(x-2)
c) y=f(-x)
d) y=f(2x)
e) y=f(x)-3
f) The y-intercept of the curve f(x)+a is 0 (zero). Write down the value of the constant a.

𝑥+3
The curve passes through the origin and has two asymptotes, with equations y = 1 and x = -3, as
shown in the Figure.
