0, 11, both multiplicity 2touch, not cross, at each 0

Step-by-step explanation:

The function factors as ...

f(x) = x^4 -22x^3 +121x^2

f(x) = x^2(x^2 -22x +121)

f(x) = x^2(x -11)^2

The zeros are x=0 and x=11, each of multiplicity 2.

Because the multiplicity is even, the graph will touch at each zero, not cross.
