Pertanyaan

jika f(x)=2x^3-3x^2-4x-15,maka nilai f'(-5) adalah?
tolong di bantu ya

Answer 1

f(x) = 2x^3 - 3x^2 - 4x -15
f'(x) = 6x^2 - 6x - 4
f'(-5) = 6(-5)^2 - 6(-5) - 4
= 6(25) + 30 - 4
= 150 +30 - 4
= 176

maaf kalau salah yaa

Answer 2

f(x)=2x^3-3x^2-4x-15
= 6x^2-6x-4
f'(-5) = 6(-5)^2-6(-5)-4
= 6.25+30-4
=176
