Q.
f(x) = x² + x³ - 15
f(5) = .........![]()
f(x) = x² + x³ - 15
f(5) = .........
Jawaban:
f(x) = x² + x³ - 15
f(5) = 5² + 5³ - 15
f(5) = (5 × 5) + (5 × 5 × 5) - 15
f(5) = 25 + (25 × 5) - 15
f(5) = 25 + 125 - 15
f(5) = 150 - 15
f(5) = 135
Fungsi
f(x) = x² + x³ - 15
f(5) = 5² + 5³ - 15
f(5) = (5.5) + (5.5.5) - 15
f(5) = 25 + 125 - 15
f(5) = 150 - 15
f(5) = 135
