Question

Decide whether the function is a polynomial function. If so, write it in standard form and state its degree, type, and leading coefficient.h(x) = 19x4 − 419x2 + 18:

Answer 1

$h(x)=19x^4+0x^3+(-419)x^2+0x+18$ is a polynomial, leading coefficent 19.
(standard form: is what I wrote even near that? :)) )
