(0, -1)
(4, -3)
Figure 4
NOT TO SCALE
(8,0)
y = f(x)
Figure 4 shows the curve y = f(x) which crosses the x- axis at (-2,0) and
(8, 0); and crosses the y axis at (0, -1). There is a stationary value
at (4,-3).
On two separate sets of axes, sketch the graphs of
i) y = f(x-2)
ii) y = f(-x)
In each case, show clearly the coordinates of any stationary value and where
the curve crosses an axis.
