# Singapore Has Run Out Of Graph Paper

(6)
Tuition given in the topic of Miss Loi's Car from the desk of at 9:52 pm (Singapore time)

Updated on

Regrettably, Miss Loi has been conspicuously absent from blogging activities this past week, not least due to her being mired in the neckache-inducing task of churning out her series of 2009 Exam Papers (Yes they’re really coming soon!).

On a less obvious note, it’s been awhile since she last wrote anything on the adventures of her little car, as things can get a little mundane revolving around life-threatening incidents and tragic parking tickets.

When the sun rose this morning to reveal the car in its usual daytime splendor, however, Miss Loi was encouraged to write about it again, for she’s glad in some ways that Mathematics is never far from people’s minds:

Mr Vandal, it’s highly unlikely that Singapore has run out of graph paper, but even if that should happen, a car (albeit driven by a sexy maths tutor) is most certainly NOT an appropriate medium for you to practice your graph sketching.

Furthermore, assuming you were trying to sketch an exponential graph y=ax, a > 1 (since your graphfitti resembles it the most) using the rear door of Miss Loi’s car as the y-axis, note that marks will be deducted for that unnecessarily “wavy” portion for x > 0 since all exponential curves (i.e. y=kax, k > 0, a > 0, a ≠ 1) have NO turning point and are supposed to be smooth.

Lastly, please remember to label your graph and axes the next time. 😕

Can't be! Tutors are one of the most honourable, gentle, harmless, and cuddly creatures you'll ever come across!

Oh yes thanks for pointing out the typo, Someone. Actually Miss Loi meant it to be a more general form of:

y = ax, a > 1

as it's worth noting that in most literature (incl. our current EMaths textbook) an exponential curve need not strictly be ex but can also taken to be, for e.g., 2x, 5x etc.

These are the little cut-and-paste typos that Miss Loi is capable of making during blogging when she's still hopping mad 🙁

Haha, I thought you were refering to the exponential graph, which is because you wrote in your picture; an exponential graph can be
