Jawaban:

a. -4

Penjelasan dengan langkah-langkah:

f(a) = -2a + a

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

f(4) = ((-2) × 4) + 4

f(4) = (-8) + 4

f(4) = -(8 - 4)

f(4) = -4 (A.)

$\mathbb{ \color{aqua}{ \underbrace{JAWABAN}}}$

a. (-4)

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

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

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

f(a) = -2a + a

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

Nilai f(4)

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

substitusikan a = 4

$\boxed{ \: \begin{aligned} \tt f(a) &= \tt - 2a + a \\ \tt f(a) &= \tt - a \\ \tt f(4) &= \red{ \boxed{ \green{ \bf{ - 4}}}} \end{aligned} \: }$

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

Jadi, nilai dari f(4) adalah (-4)
