You have to begin by declaring what g(f(x)) means. It means that wherever you see an x in g(x) you put in f(x).
It will look like this to start with
g(f(x)) = (f(x) + 5) / (f(x)
Now substitute into this for g(-3)
g(x^2 + 5) = (x^2 + 5 + 5)/(x^2 + 5) It's time to use some numbers.
g(- 3) = ((-3)^2 + 10)/( (-3)^2 +5)
g(-3) = ( 9 + 10 ) / ( 9 + 5)
g(-3) = (19)/14 <<<<<< answer.
C <<<< answer.
2r-20 is the answer combining the like terms and solving.
C.
6 is a constant, so we know that y is greater than or equal to 6.
x is just a variable, but it has to be positive, so it could be anything greater than or equal to 0.
Total flour = white flour + wheat flour, therefore y = x + 6.
