Turunan
1) f (x) = 3x² - 2x + 5
turunan pertama f '(x) = 2(3) x - 2 = 6x - 2
turunan kedua f "(x) = 6
*
2) f(x) = 2 x² + 4x - 6
f '(x) = 2(2) x + 4 = 4x + 4
f " (x ) = 4
3) f(x) = 1/√x = x^(-1/2)
f '(x) = -1/2 (x)^(-3/2)
f " (x) = - 3/2 (-1/2) (x)^(-5/2)
f " (x) = 3/4 x^(5/2)
f "(x) = 3 / (4 x²√ x)
