    Kwa mazoezi yafuatayo, onyesha kama kazi ni kazi ya polynomial na, ikiwa ni hivyo, kutoa kiwango na mgawo wa kuongoza.

    7. \(f(x)=4 x^{5}-3 x^{3}+2 x-1\)

    8. \(f(x)=5^{x+1}-x^{2}\)

    9. \(f(x)=x^{2}\left(3-6 x+x^{2}\right)\)

    Kwa mazoezi yafuatayo, tambua tabia ya mwisho ya kazi ya polynomial.

    10. \(f(x)=2 x^{4}+3 x^{3}-5 x^{2}+7\)

    11. \(f(x)=4 x^{3}-6 x^{2}+2\)

    12. \(f(x)=2 x^{2}\left(1+3 x-x^{2}\right)\)
