Turunan ax^n= an x^n-1 turunan a= 0jadi turunan ffx) = 2(2)x^2-1 - 5(1) x^1-1+0
f(x)= 4x-5
Verified answer
Turunan.Kelompok wajib kelas XI kurikulum 2013 revisi 2016.
f(x) = 2x² - 5x + 3
f(x + h) = 2(x + h)² - 5(x + h) + 3
= 2x² + 4xh + 2h² - 5x - 5h + 3
Definisi turunan adalah f'(x) = lim h→0 [f(x + h) - f(x)] / h
f'(x) = lim h→0 [f(x + h) - f(x)] / h
= lim h→0 [2x² + 4xh + 2h² - 5x - 5h + 3 - (2x² - 5x + 3)] / h
= lim h→0 (4xh + 2h² - 5h) / h
= lim h→0 (4x + 2h - 5)
= 4x + 2(0) - 5
= 4x - 5
