Using an online tool, determine the number of zeros (i.e., the number of times the function makes contact with the $x$-axis) of the polynomial $f(x)=x^5 + 2.8 x^4 + 5.96 x^3 + 11.2 x^2 + 7.84 x$. Again using this online tool, estimate these zeros. Is the multiplicity of each zero even or odd?

Number of zeros:

Estimation and multiplicity (select all that apply):

A. $(-1.4, 0)$, odd multiplicity
B. $(0, 0)$, odd multiplicity
C. $(1.4, 0)$, even multiplicity
D. $(-2, 0)$, even multiplicity
E. $(-1.4, 0)$, even multiplicity
F. $(0, 0)$, even multiplicity
