Answer:
d.−1.4, 3.4
Explanation:
Given
[tex]f(x) = x^4-3x^3-2x^2+3x-5[/tex]
Required
Determine the zeros
The best way to solve this is to apply the graphical method.
First, we plot the graph of: [tex]f(x) = x^4-3x^3-2x^2+3x-5[/tex]
See attachment
Next, we write out all values of x when the line crosses the y-axis.
From the attached graph, the points are (approximately):
[tex]x =-1.449[/tex]
[tex]x = 3.449[/tex]
Option (d) is the closest to the above values.
Hence, the zeros are: -1.4 and 3.4
