Question

Tolong pake caranya ya

Answer 1

F(x) = y
f`¹ (y) = x
f`¹(4x + 3) = 6x
f(6x) = 4x + 3
misal p = 6x maka x = 1/6p
f(p) = 4(1/6p) + 3
f(p) = (2/3)p + 3
f(x) = 2/3x + 3
fof(x) = (2/3)(2/3x + 3) + 3
fof(x) = 4/9x + 2 + 3
fof(x) = 4/9x + 5
fofof(x) = 4/9(2/3x + 3) + 5
fofof(x) = 8/27x + 4/3 + 5
fofof(x) = 8/27x + 4/3 + 15/3
fofof(x) = 8/27x + 19/3
b.(fogoh)`¹(x) = 1/2(3x - 5)
y = 1/2(3x - 5)
2y = 3x - 5
2y + 5 = 3x
⅓(2y + 5) = x
x = ⅓(2y + 5)
fogoh(x) = ⅓(2x + 5)
f(x+6) = ⅓(2x + 5)
f(-2) = ...
lihat dalam kurung
x + 6 = -2
x = -8
f(-8) = ⅓(2x + 5)
= ⅓(2(-8) + 5)
= ⅓(-16 + 5)
= -11/3
