The end behavior of the following polynomial function is option A.
The leading term of the polynomial is 20x^20, degree of f(x) = 20, and the leading coefficient is 20.
Given function:
f(x)=−2x^3+20x^20+20x^18+60x^7+9
= 20x^20+20x^18+60x^7+2x^3+9
Here the degree is 20.
Leading term = 20x^20.
Leading coefficient = 20.
The degree is even and the leading coefficient is positive so end behavior is upward parabola which is option A .
Therefore the leading term of the polynomial is 20x^20, degree of f(x) = 20, and the leading coefficient is 20.
