In the polynomial function f(x)=1/2x^2+8-5x^3-19x what is the leading the coefficient

-5

Step-by-step explanation:

The leading term in a polynomial consist on the highest degree term.  To get the highest degree term, we need to reorder the polynomial from left to right, starting with the highest degree term.

In this case:

reordering

So, the leading coefficient is the one with the leading term:

So, it is -5
