Find the roots of the polynomial equation. x^3-4x^2+x+26=0

The root of the polynomial is equal to

Step-by-step explanation:

we have

we know that

The roots of the polynomial are the values of x when the value of the polynomial is equal to zero ( x-intercepts)

Using a graphing tool

see the attached figure

The polynomial has only one x-intercept

For -----> the value of the polynomial is equal to zero

therefore

The root of the polynomial is equal to

the awnser is visionary

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
