Simple question but how draw this graph (1 Viewer)

Here's a graph of the function (hopefully you'll see how to do it by looking at what it's meant to be):
Found the assymptotes but dunno how to draw it

I always get paranoid during exams about graphs, so after I complete the questions, I compare the properties while graphing it using my calculator, I know it's a bit cheap but my calculator can graph any curve. After checking if it's odd/even/neither first

Didn't know graphing calculators were allowed in HSC!
See http://www.boardofstudies.nsw.edu.au/hsc_exams/calculators.html
As it says there, one of the features of calculators that is not allowed in the HSC is "capable of storing, manipulating or graphing functions entered in symbolic form (this includes calculators with a graphic display capacity)". You should probably get an approved calculator soon.

Never mind InteGrand beat me to it
sorry guys!! for not clarifying, what I meant was for example f(x) = x^2, I would type in my calculator (answer)^2 then press AC, I would then for example let x=1, so I press 1 and then equals, then I press up then equals again, this gives me the y-value of the curve instantly.
This is particularly useful when examining a little bit to the right of asymptotes and verifying your work and getting very quick y value results. If there is an asymptote at x = 1, I would type 1.1 =, then up arrow, then =. I would get like 900000, which is very far up, which means it is going towards infinity from the right of the asymptote. I could also work out very quickly the horizontal asymptotes by letting x = 90000000 for example.
It's just a really quick way to get y-values and also check if your graph is spot on. Works with inverse trig graphs too, and complicated trig graphs, or any graph at all I should say
- max/min
- intercepts
- endpoints
- getting the y-value of the stationary points
- asymptotic discussion
- where the curve is generally
Also verrrry very useful in confirming your answers to an equation, for example you got 4 answers for a trig question with a long process, and you might have possibly went wrong somewhere
It's just the quick process of doing , AC -> number -> equals -> up -> equals ----> repeat.

If InteGrand had a dollar for everytime he's done this just over the past week he'd be a millionaire
