(gof)(x)=g(f(x))
(gof)(4)=g(f(4))

g(f(4))
find f(4) first
f(4)=4(4)-7=16-7=9

g(f(4))=g(9)=9+3=12

(gof)(4)=12

the domain is the usable numbers
(fog)(x)
look at each
f(x)=2/x
x can be any number except 0
find what x in g(x) results in 0
0=|x|-1
add 1
1=|x|
1=x
-1=x

domain of (fog)(x) is all real numbers except for x=-1 and 1

To mix weed killer with water correctly it is necessary to mix 6 teaspoons of weed killer with 2 gallons of water. Find how many

igomit [66]

The correct proportion for mixing weedkiller with water is;

$6\text{tsp:}2\text{gal}$

When the entire box contains 12 teaspoons of weedkiller, we would now have;

$\begin{gathered} \frac{6}{2}=\frac{12}{x} \\ \text{Where;} \\ x=\text{gallons of water} \\ \text{Cross multiply and we'll have;} \\ x=\frac{12\times2}{6} \\ x=4 \end{gathered}$

ANSWER:

To mix 12 teaspoons of weedkiller, 4 gallons of water is needed.
