Answer:
M
Step-by-step explanation:
A quartic equation/function is a fourth degree polynomial. The general form is:
[tex]ax^4+bx^3+cx^2+dx+e[/tex]
We can put any values for the variables a, b, c, d, and e.
The general shape of a fourth degree polynomial is in the shape of the English letter "W".
The leading coefficient is the value of "a".
If a is negative, the curve gets upside down, so a "W" going upside down would resemble an "M".
A graph of a quartic with negative leading coefficient is shown attached. The equation is:
[tex]-x^{4}+2x^{3}+x^{2}-2x-2[/tex]
