f(-2) = ...

f(x) = 8x² + x² - x

f(-2) = 8 ( -2 )² + ( -2 )² - ( - 2 )

f(-2) = 8 ( -2 × -2 ) + ( -2 × -2 ) + 2

f(-2) = 8 ( 4 ) + 4 + 2

f(-2) = 32 + 4 + 2

f(-2) = 36 + 2

f(-2) = 38

Jawaban:

f(x) = 8x² + x²- x

f(-2) = 8 × (-2)² + x² - x

f(-2) = -16² + x² - x

f(-2) = (16 + 16) + x²- x

f(-2) = 32 + x² - x

f(-2) = 32 + (-2)² - x

f(-2) = 32 + (2 + 2) - x

f(-2) = 32 + 4 - x

f(-2) = 32 + 4 - (-2)

f(-2) = 32 + 4 + 2

f(-2) = 36 + 2

f(-2) = 38 ✓
