diketahui f(x)=3x+7 dan g(x)=2x+5.jika (fog) (p)=2,nila dari p=....

(fog)=f(gx)

fog = 3(2x+5)+7
fog = 6x + 22

(fog)(p)=2
6p + 22 = 2
6p = -20
p= -20/6 = -10/3

Diketahui
[tex] f(x)=3x+7[/tex]
dan
[tex]g(x)=2x+5[/tex]
Maka diperoleh
[tex](f \circ g)(p)=2 \\ f(g(p))=2 \\ f(2p+5)=2 \\ 3(2p+5)+7=2 \\ 6p+15=-5 \\ 6p=-20\\ \therefore p= -\frac{10}{3}[/tex]
