Given: The function .
To sketch the graph of the given function.
Concepts Used :
The points at which are known as the zeroes of the function. For zeroes with odd multiplicity the graph intersects the -axis at that value. For zeroes with even multiplicity the graph touches the -axis at that point.
If at each point of an interval , then the function is said to be increasing on that interval. If at each point of an interval , then the function is said to be decreasing on that interval. If , then is known as the critical point of the function.
If at each point of an interval , then the function is concave up in that interval. If at each point of an interval , then is concave down in that interval. If , then is known as the inflection point of the function.
