How are translations and reflections represented as a function?​ will give and everything

? A vertical reflection is given by the equation y=−f(x) and results in the curve being "reflected" across the x-axis. A horizontal reflection is given by the equation y=f (−x) and results in the curve being "reflected" across the y-axis.

Step-by-step explanation:

A vertical reflection is given by the equation y=−f(x) and results in the curve being "reflected" across the x-axis. A horizontal reflection is given by the equation y=f (−x) and results in the curve being "reflected" across the y-axis. You can see that the reflections are presented in the terms of a function.

As for translations, the function would just increase or decrease based on the translations.  

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,
