See that denominator cannot be zero, so,
x-3 ≠ 0 x ≠ 3
Domain:
S={x∈R/x≠3}
x − 3 = 0 x = 3 D : x ∈ R ∖ { 3 }
The domain of the function is all real numbers except for 3, since the function is undefined at this value. This can be expressed as S = { x ∈ R ∣ x = 3 } . Simply put, we must exclude any value that makes the denominator of the function zero.

Jawaban:Panjang langkah (stroke) kruk as dihitung dengan rumus: Stroke = Diameter Kruk As - (Diameter Big End + 2 x Tebal Ujung Daun) Substitusikan nilai yang diberikan: Stroke = 112 mm - (30 mm + 2 x 6 mm) = 112 mm - (30 mm + 12 mm) = 112 mm - 42 mm = 70 mm Jadi, panjang langkah (stroke) kruk as tersebut adalah 70 mm.
