d. (f/g) (-1)​

diketahui f(x) =2x-1 dan g(x) =3x+2
tentukan :
a. (f+g) (-2)
b. (f-g) (3)
c. (f.g) (0)
d. (f/g) (-1)​

Jawab:

Penjelasan dengan langkah-langkah:

a.

[tex](f+g)(-2)=f(-2)+g(-2)\\ =(2(-2)-1)+(3(-2)+2)\\=-5+(-4)\\=-9[/tex]

b.

[tex](f-g)(3)=f(3)-g(3)\\=(2(3) -1)-(3(3)+2)\\=(5)-(11)\\=-6[/tex]

c.

[tex](f.g)(0)=f(0).g(0)\\=(2.0-1).(3.0+2)\\=(-1).(2)\\=-2[/tex]

d.

[tex](\frac{f}{g})(-1)=\frac{f(-1)}{g(-1)}\\=\frac{2.(-1)-1}{3.(-1)+2}\\=\frac{-3}{-1}\\=3[/tex]
