Suatu fungsi dirumuskan dengan f(x) = ax²-5 . jika f¹(13) = -3 , nilai a =

Takamori37 F(x) = ax^2 - 5
f'(x) = 2ax + 0
f'(13) = -3
2a.13 = -3
26a = -3
a = -3/26

Dhimas03 makasih ya ?

Takamori37 Iya

salsabilasri1 F(x)=ax²-5 jika f(13) = -3

f(x)=ax²-5
f(13)=-3-(-5)
=-3+5=2
A= 2

Maaf ya kalau salah
