Respuesta :
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
[tex]f(x)=3x^2-0.2x^5+7x^3[/tex]
We rewrite in standard form to obtain,
[tex]f(x)=-0.2x^5+7x^3+3x^2[/tex]
Note that writing in standard form means writing in descending powers of x.
The coefficient of the leading term is -0.2.
