Question

Analyze the zeros of f(x)=^4-3x^3-2x^2+3x-5

Answer 1

Answer:

d.−1.4, 3.4

Explanation:

Given

$f(x) = x^4-3x^3-2x^2+3x-5$

Required

Determine the zeros

The best way to solve this is to apply the graphical method.

First, we plot the graph of: $f(x) = x^4-3x^3-2x^2+3x-5$

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):

$x =-1.449$

$x = 3.449$

Option (d) is the closest to the above values.

Hence, the zeros are: -1.4 and 3.4
