Jika diketahui fungsi f(x) = 5x+2/3x-1, x tidak sama dengan ⅓ dan g(x) = 3x+2, maka (f-¹ o g) (1) adalah..... a. 16/35 b. 15/24 c. 7/8 d. 34/56 e. 6/4

g(x) = 3x + 2
g(1) = 3.1 + 2 = 5

f(x) = dx + b/cx + d
f-¹(x) = -dx + b/cx - a

f(x) = 5x + 2/3x - 1
f-¹(x) = x + 2/3x - 5

(f-¹ o g)(1) = f-¹ (g(1))
= f-¹ (5)
= (5 + 2)/3.(5) - 5
= 7/10
