Especially if you don't know the material

anonymous · Answer

but its due tomorrow is the thing

rane · Answer

The original equation to this function which is reciprocal is y= \frac{ a }{ b(x-c)} +d

Where:
a is the dilation factor parallel to the y axis
b is the dilation factor parallel to the x-axis 
c is the amount of units translated to the right ( if it was (x+c) then  the translation would've been to the left).
d is the amount of units translated upwards. (if it was - d then translation would've been downwards)

rane · Answer

$$y= \frac{ a }{ b(x-c)} +d $$

anonymous · Answer

alright

rane · Answer

yup. The equation could be upside down. 
Like in your question, the equation is other way around but its alright it means the same thing. 

Hope you got it !
