test cheat sheet

This is a draft cheat sheet. It is a work in progress and is not finished yet.

### Solving domain and range

 y=x2+x-2/x2-x-2 domain­-->­[fu­nct­ion­]ra­nge­-->

### Family function (trans­for­mation)

 y=a`0` f(ax-h)-k y=c is a horizontal line y=x the pints on the graph have points (a,a) y=x2 graph is shaped like a U y=x3 graph is symmet­rical about the origin y=1/x graph has to branches y=|x| graphed like a V y=[[x]] is greater than the integer less than or equal to x

### Trigon­ometry

 Log`b`(mn)=n*Log`b`(m) 1.) Multiply the inside log and turn into addition outside the log and vice verse 2.)divide inside the log and turn into subtra­ction outside the log, vice versa 3.)exp­onent on everything inside a log can be moves out in front as a multip­lic­ation, vice versa. The Relati­onship: "­logb(x) = y" means the same thing as "b y = x" Logarithms are really exponents (powers); they're just written differ­ently logb(b) = 1, for any base b, because b1 = b logb(1) = 0, for any base b, because b0 = . logb(a) is undefined if a is negative logb(0) is undefined for any base . logb(bn) = n, for any base b
