4 Decide whether the function is a polynomial function. If so, write it in standard form and state its degree, type, and leading coefficient.
h(r) =345-101-2+473+
4
A
polynomial function; h(x) = 3~3 + 1
+x - 101-2 + 4x; 4 (linear), leading coefficient: 3
B
polynomial function; h(1) = 479 - 101 + 5 x+3/3; 3 (cubic), leading coefficient: 4
С
not a polynomial function
D
polynomial function; #(x) =3~3+
4
:x - 104-2 + 403;3 (cubic), leading coefficient.
