Question

Determine whether the function h left parenthesis x right parenthesis equals 6 x cubed minus one half x plus 8 is a polynomial function. If it is a polynomial​ function, then state the degree and leading coefficient.

Answer 1

$h(x) = (6x)^{3} - 1.5 x + 8 = 216 {x}^{3} - 1.5x + 8$

h is polynomial and its degree is 3 and the leading coefficient is equal to 216
