$\mathbb \color{orange} \underbrace{PENYELESAIAN}$

$\underline{ \overline{ \boxed{ \bold{diketahui}}}}$

f(x) = 4x + 7 - 2x

$\\ \underline{ \overline{ \boxed{ \bold{ditanya}}}}$

f(2a + 1)

$\\ \underline{ \overline{ \boxed{ \bold{jawab}}}}$

=> substitusikan x = 2a + 1

$\begin{aligned} \sf f(x) &= \sf 4x + 7 - 2x \\ \sf f(2a + 1) &= \sf 4(2a + 1) + 7 - 2(2a + 1) \\ \sf f(2a + 1) &= \sf 8a + 4 + 7 - 4a - 2 \\ \sf f(2a + 1) &= \bold{4a + 9}\end{aligned}$

------------------

$\mathbb \color{red} \underbrace{KESIMPULAN}$

Jadi, nilai f(2a + 1) adalah 4a + 9
