The axis of symmetry is x = 5.
The y-intercept of the function is (0, 5).

Answer:

Step-by-step explanation:

The first statement, the fourth statement, and the fifth statement are true.  The others are not.  

In vertex form, looking at the first statement, you can see that the vertex is located at (4, -11), NOT (-8, 5)

The (x - 4)^2 binomial gives you the axis of symmetry, which is x = 4, NOT x = 5.
