Chapter 4 - Section 4.9 - Antiderivatives - 4.9 Exercises - Page 355: 19

$F(x)=\displaystyle \frac{2^{x}}{\ln 2}+4\cosh x+C$

From the Table of Antiderivatives, $f(x)=b^{x}\displaystyle \quad \Rightarrow\quad F(x)=\frac{b^{x}}{\ln b}+C$ $f(x)=\sinh x\quad \Rightarrow\quad F(x)=\cosh x+C$ --- $f(x)=2^{x}+4\sin h$ $F(x)=\displaystyle \frac{2^{x}}{\ln 2}+4\cosh x+C$
