Answer:
a. 2
Step-by-step explanation:
The given function is
[tex]f(x)=x^4-3x^3-2x^2+3x-5[/tex].
We can see from the graph that the graph has two x-intercepts.
This means that the function has two real zeros.
By the fundamental theorem of Algebra, the function is supposed have four roots since it is a polynomial of degree 4.
Therefore, the other two zeros are complex.
