    g(-8) = 6(-8) + 1 = ? then replace the x in f(x) by this results

    so that will be f(-8) =5(-8)+5 @welshfella

    You have to do it in order. 1) Find the value of g(-8) 2) Now your new value for "x" to use in f(x) is the value you just found g(-8) so you would have x=g(-8) and you should evaluate f(x) in you new "x" value (g(-8)) 3) At the end you should have something like f(g(-8))=5g(-8)+5

    okay so i did g(-8) = 6(-8) + 1 = ? and got -47 so now i do this f(-47)=5(-47)+5

    Match the correct graph to the function shown. f(x)=2sqrt3−4x +3

    try wolphramalpha.com it's really good at drawing this type of functions. And it's free for this feature. Plus you dont need to download anything
