Find all zeros of ƒ(x)=x4–22x3+121x2.Then determine the multiplicity at each zero. State whether the graph will touch or cross the x-axis at the zero.

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.

the answer is 489

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
