Graph of the Reciprocal of a Function

Reciprocal of a Function

The following guidelines are useful in order to sketch the reciprocal of a function given the graph of the original function:


Where is positive or negative then is also positive or negative respectively.

Where has zero(s) then the reciprocal function has vertical asymptote(s) and vice versa.

Where has a horizontal asymptote at y=c then the reciprocal function has also horizontal asymptote at .

Where the original function is increasing then the reciprocal function is decreasing.

Where the original function is decreasing then the reciprocal function is increasing.

If the original function has a maximum at then the reciprocal function has a minimum at .

If the original function has a minimum at then the reciprocal function has a maximum at .

If the original function has a point of inflexion at then the reciprocal function has also a point of inflexion at .

IB Maths HL, SL, Studies Past Papers

One way is to search on Google the following phrase:
“M12/5/MATHL/HP1/ENG/TZ1/XX” in order to find for example the past paper 1 of May 2012 in English of Time Zone 1.
If you want additionally the corresponding markscheme of this paper then you will find it by searching on Google the following phrase
“M12/5/MATHL/HP1/ENG/TZ1/XX/M”

Some of the Google results correspond to official IBO website in order to purchase this past paper which is actually the only legal way and is strongly recommended from this community.

Another way is going directly to the official website of IBO http://www.ibo.org or https://store.ibo.org/diploma-programme ... cheme-pack and search there for the specific past paper.
