Convert the equation into a standard form
y=x2+4x+4
y= (x+2)^2
From the equation
vertex is located at (-2,0)
Solve for a to get the coordinates of the focus, from the equation
4a=1
a=1/4
Focus is located at (-2, 1/4)
The equation of the directrix
y=-1/4
2(4)-3 is what f(4) is equal to if you imput 4 for x. Distribute 2 to the 4 to get 8-3 so f(4) is equal to 5!
