To view the CALC menu, press
Choose option 7 Inflec to find the point(s) of inflection where the graph changes concavity.

Press and enter the function

y = (x-2)^{2}(x+2)(x+5)

There is more than one point of inflection.
Reflect the graph about the x axis and simply run Inflect again.
Press and enter the function

y = **-**(x-2)^{2}(x+2)(x+5)
