f(x)=x2ln(x)
- What is the domain of the function?
- Does this function have any intercepts with the axis?
- What are the turning points?
- What is the x value of the point of inflection?
- Sketch the graph.
Answers:
- x>0
- f(x)=0=x^2 ln(x) x=1 f(x) has a x-intercept at (1,0).
- f ‘(x)=2x ln(x)+x=0 x=0 & x=e^(-1/2)
- f ”(x)=3+2ln(x)=0 x=e^(-3/2)
