Diketahui f(x)= 4 x + 3 dang(x) = 1/2(x-5) nilai dari (g o f)^-1 (5)=…

semoga membantu, jangan lupa kasih MAHKOTA yaa, makasih lohh 🙂

Gambar Jawaban

(gof)(x)=(g(4x+3))

(gof)(x)=(4x+3-5)/2

(gof)(x)=(4x-2)/2

(gof)(x)=2x-1

misal a= 2x-1

2x=a+1

x=(a+1)/2

(gof)^-1(x)=(x+1)/2

(gof)^-1(5)=(5+1)/2

(gof)^-1(5)=6/2 = 3
