<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:

In which a is the leading coefficient.
In this problem, the maximum value was a share value of $18 after 10 days, hence the vertex is:
(h,k) = (10,18).
Thus:

Since the initial price was of $8 per share, we have that:




Hence the equation is:

At the end of the answer, the sketch of the graph is given.

Answer:
X=4
Step-by-step explanation:
Step 1: Subtract 2 from both sides.
3x+2−2=14−2
3x=12
Step 2: Divide both sides by 3.
3x
