f(x) = x(8) + x³ - x⁶ + (x ÷ x)² + x²
f(8) = 8(8) + 8³ - 8^6 + ( 8÷8 )² + 8²
f(8) = 64 + 512 - 262.144 + ( 1 )² + 64
f(8) = 576 - 262.144 + 1 + 64
f(8) = -261.568 + 1 + 64
f(8) = -261.567 + 64
f(8) = -261.503
______________________
f(x) = 6x² + 4x² - 7x + 2x
f'(x) = 10x² - 5x
f'(x) = ( 2 × 10 )x^(2-1) - 5x^(1-1)
f'(x) = 20x¹ - 5x^0
f'(x) = 20x - 5(1)
f'(x) = 20x - 5
f'(3) = 20(3) - 5
f'(3) = 60 - 5
f'(3) = 55
Penyelesaian ☁️
Nomor 1
f(x) = x(8) + x³ - x⁶ + (x ÷ x)² + x²
f(8) = 8(8) + (8×8×8) - (8×8×8×8) + ( 8÷8 )² + (8×8)
f(8) = 64+ 512 - 262.144+ (1)2 + 64
f(8) 576-262.144 + 1 + 64
f(8)= -261.568 +1 +64
f(8)= -261.567 + 64
f(8)= -261.503 ✅
______________________
f(x) = 6x² + 4x² - 7x + 2x
f'(x) = 10x² - 5x
f'(x) = (2x 10 )x(²-¹) - 5x¹-¹
f'(x) = 20x¹ - 5x⁰
f'(x) = 20x - (5×1)
f'(x) = 20x-5
f'(3) = ( 20×3 ) - 5
f'(3) = 60 - 5
f'(3) = 55
