Answer:
a.
.
b. The axis of symmetry for
is
.
Step-by-step explanation:
a. The vertex form of a quadratic is given by
, where (h, k) is the vertex.
To convert from
form to vertex form you use the process of completing the square.
Step 1: Write
in the form
. Add and subtract 4:

Step 2: Complete the square 

b. The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola.
For a quadratic function in standard form,
, the axis of symmetry is
.
The axis of symmetry for
is
.
Look at the graph shown below.
Answer:
Total people international traveler on cruises = 1,425 million people
Step-by-step explanation:
Given:
Total people international traveler on cruises = 28.5 million
