Find both of the two [tex]\( x \)[/tex]-intercepts of the function

[tex]\[
f(x) = \frac{(x-20)(x+9)}{x(x-12)}.
\][/tex]

Smaller intercept at [tex]\( x = \square \)[/tex]

Larger intercept at [tex]\( x = \square \)[/tex]


Sagot :

To find the [tex]\( x \)[/tex]-intercepts of the function [tex]\( f(x) = \frac{(x-20)(x+9)}{x(x-12)} \)[/tex], we need to determine where the function crosses the [tex]\( x \)[/tex]-axis. This occurs when the numerator is zero and the denominator is non-zero.

The numerator of the function is [tex]\((x-20)(x+9)\)[/tex]. We set this equal to zero to find the [tex]\( x \)[/tex]-intercepts.

[tex]\[ (x-20)(x+9) = 0 \][/tex]

This equation will be zero when either [tex]\( x-20 = 0 \)[/tex] or [tex]\( x+9 = 0 \)[/tex].

1. Solving [tex]\( x-20 = 0 \)[/tex]:
[tex]\[ x = 20 \][/tex]

2. Solving [tex]\( x+9 = 0 \)[/tex]:
[tex]\[ x = -9 \][/tex]

Thus, the [tex]\( x \)[/tex]-intercepts of the function are [tex]\( x = 20 \)[/tex] and [tex]\( x = -9 \)[/tex].

Finally, we identify the smaller and larger intercepts:
- Smaller intercept at [tex]\( x = -9 \)[/tex]
- Larger intercept at [tex]\( x = 20 \)[/tex]

Therefore:
Smaller intercept at [tex]\( x = -9 \)[/tex] [tex]\(\square\)[/tex]

Larger intercept at [tex]\( x = 20 \)[/tex] [tex]\(\square\)[/tex]
