Answer :
To solve the problem of finding the values of [tex]\( x \)[/tex] for which [tex]\( f(x) = 15 \)[/tex] when [tex]\( f(x) = 4|x-5| + 3 \)[/tex], let's go through the steps:
1. Set the Function Equal to 15:
Start by setting the function equal to 15:
[tex]\[
4|x-5| + 3 = 15
\][/tex]
2. Isolate the Absolute Value:
Subtract 3 from both sides to isolate the absolute value expression:
[tex]\[
4|x-5| = 12
\][/tex]
3. Divide to Solve for the Absolute Value:
Divide both sides by 4:
[tex]\[
|x-5| = 3
\][/tex]
4. Create the Two Possible Equations:
Because the absolute value of a number [tex]\( |a| = b \)[/tex] implies two possible scenarios—[tex]\( a = b \)[/tex] or [tex]\( a = -b \)[/tex]—we can set up two separate equations:
- Equation 1: [tex]\( x - 5 = 3 \)[/tex]
- Equation 2: [tex]\( x - 5 = -3 \)[/tex]
5. Solve Each Equation:
For the first equation [tex]\( x - 5 = 3 \)[/tex], add 5 to both sides:
[tex]\[
x = 3 + 5 = 8
\][/tex]
For the second equation [tex]\( x - 5 = -3 \)[/tex], add 5 to both sides:
[tex]\[
x = -3 + 5 = 2
\][/tex]
6. Conclusion:
The values of [tex]\( x \)[/tex] for which [tex]\( f(x) = 15 \)[/tex] are [tex]\( x = 8 \)[/tex] and [tex]\( x = 2 \)[/tex].
Thus, the solution corresponds to the option: [tex]\( x = 2, x = 8 \)[/tex].
