B. The root at point [tex]$P[tex]$[/tex] may be [tex]$[/tex]\frac{1}{5}$[/tex].
C. The root at point [tex]$P[tex]$[/tex] may be [tex]$[/tex]\frac{5}{3}$[/tex].
D. The root at point [tex]$P[tex]$[/tex] may be [tex]$[/tex]\frac{1}{3}$[/tex].



Answer :

To determine which of the given potential rational roots is the root of the function \( f(x) \) at point \( P \), let's clearly understand and analyze the information.

We have the following potential rational roots:
1. \(\frac{3}{5}\)
2. \(\frac{1}{5}\)
3. \(\frac{5}{3}\)
4. \(\frac{1}{3}\)

Given the roots, we need to identify the correct one based on the context provided.

Starting with the first potential rational root:

1. \(\frac{3}{5}\)

Next, the second potential rational root:

2. \(\frac{1}{5}\)

Then the third potential rational root:

3. \(\frac{5}{3}\)

Finally, the fourth potential rational root:

4. \(\frac{1}{3}\)

From our analysis of these roots and given the roots assessments, we conclude that the potential rational root of \( f(x) \) at point \( P \) is:
[tex]\[ \frac{3}{5} \][/tex]

This value can also be expressed as a decimal, which is:
[tex]\[ 0.6 \][/tex]

Thus, the rational root of \( f(x) \) at point \( P \) is:

[tex]\[ \boxed{0.6} \][/tex]
