himpunan penyelesaian pertidaksamaan 13 - 4x per x - 2 <0

misalkan [tex]f(x)=\frac{13-4x}{x-2}[/tex]
[tex]13-4x=0\\x=\frac{4}{13}\\\\x-2=0\\x=2[/tex]
kita lakukan titik uji coba, misal aja 0
[tex]x=0\rightarrow \frac{13-4\times 0}{0-2}=-\frac{13}{2}<0\\\\\therefore \forall x\leq\frac{13}{4} \left(f(x)\leq 0\right)\\\forall \frac{13}{4}\leq x<2\left(f(x)>0\right)\\\forall x>2\left(f(x)<0\right)\\\\\therefore HP=\{x\leq\frac{13}{4}\vee x>2\}[/tex]
