Answer:

(-2, 3)

Explanation:

The vertex of an absolute value function is when the part of the equation that is inside absolute value signs is equal to 0:

In the equation: y = |x + 2| + 3,

x + 2 = 0 ==> x + 2 is the part that is inside the absolute value signs

x = -2 ==> subtract 2 on both sides

Now, plugin -2 into the equation y = |x + 2| + 3:

y = |(-2) + 2| + 3

y = |0| + 3

y = 0 + 3 ==> the absolute value of 0 is 0.

y = 3

Now with the x and y-coordinates, we can figure out the vertex point:

Answer: (-2, 3)
