The vertex of the function is at x = -3/2. We cannot find the y value with an incomplete equation.
To find the x value of a vertex, we use the equation -b/2a, in which a is equal to the coefficient of x^2 (in this case 1) and b is equal to the coefficient of x (in this case 3).
-b/2a
-3/2(1)
-3/2
This gives us that value. To find the y value, you would plug this into the equation. Since this equation is not complete, you cannot do that yet.
Convert your feet to inches. So 8 times by 12 = 96 inches if you have 3/4 of the board used. 3/4= .75 if you were to times 96 by .75 = 72 inches. So you used 72 inches and you have 24 inches left
now do 1/3= .33 times .33 by 24= 8 8 inches is how long you would give to Anthony's brother.
