The vertex can be labeled at
​
( -4, 2 )
Two other points we will note are at x = -3 and x = -5
Both lie at value y = 4
​
(-3, 4) and (-5, 4)
​
Let us find the slope between these points. To find (a) we need to take our vertex as well as a point we made, a point that lies on the right side of the line graph. With respect to the vertex.
​
In our graph this point is (-3, 4)
Our vertex, recall, (-4, 2)
​
with this, a =
​

(h, k) is our vertex!!
NEW LETTERS ALERT!!!!
(h, k) = vertex = ( -4, 2 )
(x, y) = Chosen Right-Side Point = ( -3, 4 )
LET THE DRUM ROLL
f(x) = 2|x + 4| + 2
