Minggu paling terburuk dalam sejarah :'
f(x) = x² + x! - x
f(5) = 5² + 5! - 5
f(5) = (5 × 5) + 5! - 5
f(5) = 25 + (5 × 4 × 3 × 2 × 1) - 5
f(5) = 25 + 120 - 5
f(5) = 145 - 5
f(5) = 140

Penjelasan dengan langkah-langkah:
[tex] \red{ \sf \: f(x)} = \sf {x}^{2} + x! - x[/tex]
[tex] \red{ \sf \: f(5)} = \sf \: {5}^{2} + 5! - 5[/tex]
[tex] \red{ \sf \: f(5)} = \sf \: (5 \times 5) + (5 \times 4 \times 3 \times 2 \times 1) - 5[/tex]
[tex] \red{ \sf \: f(5)} = \sf \: 25 + (20 \times 3 \times 2 \times 1) - 5[/tex]
[tex] \red{ \sf \:f(5)} = \sf25 + (60 \times 2 \times 1) - 5[/tex]
[tex] \red{ \sf \: f(5)} = \sf \: 25 + 120 - 5[/tex]
[tex] \red{ \sf \: f(5)} = \sf \: 145 - 5[/tex]
[tex] \red{ \sf \: f(5)} = \red{\underline{ \green{ \sf \: 140}}}[/tex]
