Question

jika g(x) =5 x^2 + 4 px - 3 dan g' (2) =4 , nilai g' (1) adalah
​

Answer 1

Diketahui

g(x) = 5x² + 4px - 3

g'(2) = 4

Nilai g'(x)

g(x) = 5x² + 4px - 3

g'(x) = 10x + 4p

Nilai p

g'(x) = 10x + 4p

g'(2) = 10(2) + 4p

4 = 20 + 4p

-16 = 4p

p = -4

Nilai g'(1)

g'(x) = 10x + 4p

g'(1) = 10(1) + 4(-4)

g'(1) = 10 + (-16)

g'(1) = -6
