The given graph is the graph of a polynomial function Give t

The given graph is the graph of a polynomial function. Give the possible values for the degree of the polynomial, and give the sign ( + or _ ) for x^n term. Choose the correct answer. Polynomial function of degree 3,4, or 5 polynomial function of degree 4 polynomial function of degree 5 The sign of the leading coefficient of the function is .

Solution

number of roots =4

number of turning points =3

minimum degree of polynomial function =4

end behaviour:

as x-> , y->

as x->- ,y->

so sign leading coefficient of the function is +
