Question

.
f(x) = x² - x
f'(2) = ...?
f'(1) = ...
f'(3) = ...​

Answer 1

Verified answer

f(x) = x² - x

[tex] \sf f'(x) =2. {x}^{2 - 1} - 1[/tex]

f'(x) = 2x - 1

Sehingga:

f'(2) = 2(2) - 1 = 4 - 1 = 3

f'(1) = 2(1) - 1 = 2 - 1 = 1

f'(3) = 2(3) - 1 = 6 - 1 = 5

Answer 2

Jawab:

f'(2) = 3

f'(1) = 1

f'(3) = 5

Penjelasan dengan langkah-langkah:

f(x) = x² - x

f'(x) = (1.2.x²⁻¹) - (1.1x¹⁻¹) = 2x - 1

Jadi:

f'(2) = 2(2) - 1 = 4 - 1 = 3

f'(1) = 2(1) - 1 = 2 - 1 = 1

f'(3) = 2(3) - 1 = 6 - 1 = 5
