when doing (f o g) (-2), what do you find first? - answersg(-2) then plug in to f(x) to solve what do you do when you have a fraction within a fraction ex: 1/ (2/x+1) -4 - answersmultiply by the denominator of the extra fraction in this case, multiply by (x+1/x-1) to get rid of fraction domains for composite functions do not include (2 things) ex: f(x) = 1/x-4 and g(x) = 2/x+1 find f o g - answers1. final answer denominator can't equal 0 2. denominator can't equal 0 i...

Graphing an exponential function and its asymptote: f(x)=bx - answers1. The domain is unrestricted, so you should start with the standard "spectrum" table having x values from -2 to 2. Do the calculations and plot the points (multiply straight across and flip if you multiply by a negative) 2. You must also place the asymptote into your final product. For the basic common exponential functions, the x-axis is the asymptote Translating the graph of an exponential function - answers1. To gr...
