Question

Diketahui f(x)=x-4 dan g(x)=3x-9. Nilai dari f(3)+g(2) adalah...

Answer 1

F(x) = x-4
f(3) = 3-4 = -1

g(x) = 3x-9
g(2) = 3.2-9 = 6-9 = -3

Maaf kalo salah

Answer 2

f(3)= x-4                     g(2)= 3x-9

     = 3-4                            = 3*2-9

     = -1                              = 6-9

                                         = -3

f(3)+g(2)= -1+(-3)

              = -4
