OK. Hold on tight. Here we go.
Remember ... the "solution" is the number that 'g' must be
in order to make the equation a true statement.
The original equation: You said that -2 = g - 9
Now, let's add 9 to each side: 7 = g .
Time is 4 hrs., coffee is 0 cups. Point (4,0)
So A
F(x)=3 domain: negative infinity, positive infinity range: 3
g(x)=x+7 domain: - infinity, + infinity range: - infinity, + infinity
The area is 126in^2
Hope this helps
