Describe the graph of the function at its roots.

[tex]\[ f(x)=(x-2)^3(x+6)^2(x+12) \][/tex]

At [tex]\( x=2 \)[/tex], the graph [tex]\(\square\)[/tex] the [tex]\( x \)[/tex]-axis.

At [tex]\( x=-6 \)[/tex], the graph [tex]\(\square\)[/tex] the [tex]\( x \)[/tex]-axis.

At [tex]\( x=-12 \)[/tex], the graph [tex]\(\square\)[/tex] the [tex]\( x \)[/tex]-axis.


Sagot :

To describe the behavior of the graph of the function [tex]\( f(x) = (x-2)^3(x+6)^2(x+12) \)[/tex] at its roots, let's analyze each root in turn.

1. At [tex]\( x = 2 \)[/tex]:
- The term [tex]\((x-2)^3\)[/tex] contributes to the function becoming zero at [tex]\( x = 2 \)[/tex].
- The exponent 3 is an odd number, which means that at this root, the graph will touch the x-axis and change direction (cross the x-axis).

Therefore, at [tex]\( x=2 \)[/tex], the graph touches and crosses the x-axis.

2. At [tex]\( x = -6 \)[/tex]:
- The term [tex]\((x+6)^2\)[/tex] results in the function becoming zero at [tex]\( x = -6 \)[/tex].
- The exponent 2 is an even number, implying that at this root, the graph will touch the x-axis but will not change direction (it does not cross the x-axis).

Hence, at [tex]\( x=-6 \)[/tex], the graph touches but does not cross the x-axis.

3. At [tex]\( x = -12 \)[/tex]:
- The term [tex]\((x+12)\)[/tex] causes the function to be zero at [tex]\( x = -12 \)[/tex].
- The exponent of this term is 1, which is an odd number. This means that at this root, the graph will touch the x-axis and change direction (cross the x-axis).

Consequently, at [tex]\( x=-12 \)[/tex], the graph touches and crosses the x-axis.

Summarizing our findings:
- At [tex]\( x=2 \)[/tex], the graph touches and crosses the x-axis.
- At [tex]\( x=-6 \)[/tex], the graph touches but does not cross the x-axis.
- At [tex]\( x=-12 \)[/tex], the graph touches and crosses the x-axis.

So the completed statement is:

At [tex]\( x=2 \)[/tex], the graph touches and crosses the [tex]\( x \)[/tex]-axis.

At [tex]\( x=-6 \)[/tex], the graph touches but does not cross the [tex]\( x \)[/tex]-axis.

At [tex]\( x=-12 \)[/tex], the graph touches and crosses the [tex]\( x \)[/tex]-axis.
