Sever21 [200]
Plug \ in \ x+3 \ into \ f(x) \ to \ get \ g(x)
\\\ g(x) = (x+3)^2-2(x+3)+6
\\\ g(x)= x^2+6x+9 -2x-6+6
\\\ g(x) = x^2+4x+9
\\\ -\frac{b}{2a} --\ \textgreater \  vertex
\\\ \frac {-4}{2}
\\\ x \ coordinate = -2, plug \ it \ back \ into \ g(x)
\\\ (-2)^2+4(-2)+9
\\\ 4-8 + 9
\\\ y \ coordinate = 5
\\\ \boxed{(-2,5)}

You are using 0.05 gallons per mile of a SUV gas tank that holds 16 gallons. y = - 0.05x + 16. (Or, if you wish you may use
asambeis [7]
Here, we just use the following x values and put them into the equation.

y = - 0.05x + 16
y = -0.5(0) + 16
y = 16

y = - 0.05x + 16
y = -0.5(160) + 16
y = -80 + 16
y = -64

y = - 0.05x + 16
y = -0.5(320) + 16
y = - 160 + 16
y = -144

Now, to set up the table, you could list the x values and the y values. 

x values :- 0,160, 320
y values:- 16, -64, -144
