Given -f(x+5), what could the transformation description be? i know that f(x) is reflected over the x-axis, but would it translate 5 units to the left or five units to the right?

5units to the left.as long as the argument of the function (the stuff that will be inputted into the function; in this case it is x+5) has no coefficient on x, (+) means to the left means to the right.======side note (not related to your original question): if, for example, there was  , there has to be no coefficient on x to identify correct translations. so if you factor out a negative to get      -5) \big)[/tex]it'll actually be a reflection in the y-axis and  5 units right 

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats
