f(x)=3x-5 g(x)=x+2 A.(f+g) B.(f-g) C.(f°g) Df-¹(x)

Semoga membantu dan bermanfaat.

A.
=> f(x) + g(x)
=> 3x - 5 + x + 2
=> 4x - 3

B.
=> f(x) - g(x)
=> 3x -5 -(x + 2)
=> 2z - 7

C.
f(g(x))
f(x+2)
3×(x + 2) - 5
3x + 6 - 5
3x + 1

D.
3x - 5 = y
3x = y + 5
x= (y+5)/3

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