What is the leading coefficient of this polynomial?

The leading coefficient is the number in front of the variable with the highest degree(exponent)

The highest degree (exponent) is 5, so the leading coefficient = -0.2

ANSWER

The leading coefficient of the given polynomial is -0.2

EXPLANATION

The given polynomial function is

We rewrite in standard form to obtain,

Note that writing in standard form means writing in descending powers of x.

The coefficient of the leading term is -0.2.
