Answer:
Step-by-step explanation:
We have the quadratic function:
And we want to determine its axis of symmetry.
Notice that this is in vertex form:
Where (<em>h, k</em>) is the vertex of the parabola.
From our function, we can see that <em>h</em> = 4 and <em>k</em> = -2.5. Hence, our vertex is the point (4, -2.5).
The axis of symmetry is equivalent to the <em>x-</em>coordinate of the vertex.
The <em>x-</em>coordinate of the vertex is 4.
Therefore, the axis of symmetry is <em>x</em> = 4.
