Question
![Given the three functions below, which expression equals \((r \circ b \circ s)(x)\)?
\[ b(x) = 2^x \]
\[ r(x) = |x| \]
\[ s(x) = 7x \]
Options:
- \(|7(2^x)|\)
- \(|2^{(7x)}|\)
- \(7(2^x)\)
- \(7|2^x|\)

**Note**: In this context, the composition of functions \((r \circ b \circ s)(x)\) implies evaluating \(s(x)\) first, followed by \(b(x)\), and finally \(r(x)\).
