Qz.
f(x) = x - x × x + x - x
f(2) = ?
f(4) = ?

Penjelasan dengan langkah-langkah:

f(x) = x - x × x + x - x

f(2) = 2 - 2 × 2 + 2 - 2

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

f(2) = -2 + 2 - 2

f(2) = 0 - 2

f(2) = -2

---

f(4) = 4 - 4 × 4 + 4 - 4

f(4) = 4 - 16 + 4 - 4

f(4) = -12 + 4 - 4

f(4) = -8 - 4

f(4) = -12

$\sf f(x) = x - x \times x + x - x$

$\sf f(2) = 2 - (2 \times 2) + 2 - 2$

$\sf f(2) = 2 - 4 + 2 - 2$

$\sf f(2) = - 2 + 2 - 2$

$\sf f(2) = 0 - 2$

$\sf f(2) = \bf\blue{ - 2}$

$\sf f(4) = 4 - (4 \times 4) + 4 - 4$

$\sf f(4) = 4 - 16 + 4 - 4$

$\sf f(4) = - 12 + 4 - 4$

$\sf f(4) = - 8 - 4$

$\sf f(4) = \bf\blue{ - 12}$
