Q.
f(x) = 7x² - x + x(x) + 8x
f(2)
______
._
f(x) = 7x² - x + x(x) + 8x
f(2)
______
._
Penjelasan dengan langkah-langkah:
f(x) = 7x² - x + x(x) + 8x
f(2) = 7(2²) - 2 + 2(2) + 8(2)
f(2) = 7(4) - 2 + (2 × 2) + 16
f(2) = 28 - 2 + 4 + 16
f(2) = 26 + 4 + 16
f(2) = 30 + 16
f(2) = 46
Jawaban:
f(x) = 7x² - x + x(x) + 8x
f(2)
penyelesaian :
f(2) = 7(2)² - 2 + 2(2) + 8(2)
f(2) = 7(2×2) - 2 + (2×2) + (8×2)
f(2) = 7(4) - 2 + 4 + 16
f(2) = (7×4) - 2 + 4 + 16
f(2) = 28 - 2 + 4 + 16
f(2) = 26 + 4 + 16
f(2) = 30 + 16
f(2) = 46
