Kepencet!! O-o

...oh well
jawaban soal ini apa ya?
tolong pake caranya, tapi kalau nggak juga gpp

Answer 1

D²y/dx² = 12x² -2 --> y " (x) = 12x² - 2
y' = ∫12x² - 2 = 4x³ - 2x + c
y = ∫ y' = ∫ 4x³ -2x + c
y = x⁴ - x² + cx + C 
f(0) = -5 --> C = -5
y = x⁴ -x² + cx - 5
f(2) = 7 --> 16 - 4 + 2c - 5 = 7
c = 0

y = x⁴ - x² - 5
