Draw the rough sketch of the curve `y=(x-1)^(2)(x-3)^(3)`

Text Solution

Verified by Experts

We have `y=f(x)=(x-1)^(2)(3-x)^(3)=-(x-1)^(2)(x-3)^(3)`
The sign scheme of `y=f(x)` is as follows.

`(x-3)^(3) rarr` Curve crosses the x-axis at (3,0) and also touches the x-axis.
`(x-1)^(2) rarr ` Curve does not cross the x-axis but touches the x-axis at (1,0).
Therefore, the graph of the function is as shown in the following figure.
