Hello there.
To answer this question, we need to remember some properties about the vertex of quadratic functions.
Let 
. Its vertex can be found on the coordinates 
such that 
and 
, in which 
.
Using the coefficients given by the question, we get that:
Thus, we have:
So the statement is true, because the 
coordinate of the vertex of the function is equal to 
Answer:
x = 2
Step-by-step explanation:
The axis of symmetry is a vertical line passing through the vertex, with equation
x = c ( c is the x- coordinate of the vertex ) , then
x = 2 ← equation of axis of symmetry
