tolong ya guys nomor 2 sama 3 thankss !!!!!!

2.
a hog(x)
[tex]hog(x) = \frac{3(2x - 4) - 5}{2x - 4 + 2} \\ hog(x) = \frac{6x - 17}{2x - 2} [/tex]
b.
[tex]goh(x) = 2( \frac{3x - 5}{x + 2} ) - 4 \\ goh(x) = \frac{6x - 10}{x + 2} - 4[/tex]
Maka g o h(3)
[tex] = \frac{6(3) - 10}{3 + 2} - 4 \\ = \frac{18 - 10}{5} - 4 \\ = \frac{8}{5} - \frac{20}{5} \\ = - \frac{12}{5} [/tex]
