Question

I want to know what 2 straights around a number mean. I will post the equation I mean in the next post as I need to use the proper equation thingie.

Answer 1

\[\left| f(x) \right|\le c.g(x)\]

Answer 2

just what the straights mean.

Answer 3

oh that's the absolute value or the distance away from zero on a line graph.
|-3|=3 , but also:
|3|=3

Answer 4

ok thanks

Answer 5

Yup, no problem.

Answer 6

^That's punny :)

Answer 7

this is most likely to do with a bounding argument

Answer 8

the ML lemma for an upper bound for an integral

Answer 9

|3(x)|=6
to solve this, you would solve -3x=6 and 3x=6 separately to find your different answers.

Answer 10

|f(x)|≤c.g(x) is read as the absolute value of the function f of x is less than or equal to a constant times the function g of x

The line before and after may help

Answer 11

Oh thanks I didn't realise there were more good answers! I am trying to learn about the basics of program efficiency, for context. The function I wrote describes a linear rate of growth for a program.
