q.

diketahui fungsi f(x) = 3x³ + 4x³ . maka tentukan turunan pertama f'(2)

==============
gunakan cara
jangan ngasal

f(x) = 3x³ + 4x³

f(x) = (3 + 4)x³

f(x) = 7x³

f'(x) = 3(7x³-¹)

f'(x) = 21x²

f'(2) = 21(2)²

f'(2) = 21(4)

f'(2) = 84

f(x) = 3x³ + 4x³

f'(x) = (3.3)x^(3 - 1) + (4.3)x^(3 - 1)

= 9x² + (4.3)x^(3 - 1)

= 9x² + 12x²

f(-2) = 9(-2)² + 12(-2)²

= 9(4) + 12(4)

= 36 + 48

= 84

atau :

f(x) = 3x³ + 4x³

= 7x³

f'(x) = (7.3)x^(3 - 1)

= 21x²

f(-2) = 21(-2)²

= 21(4)

= 84
