Answer:
The vertex of the quadratic function is:

Step-by-step explanation:
Given the function

As the vertex of the form
is defined as:

As the quadratic function of parabola params are

so



Putting
to determine 




Therefore, the vertex of the quadratic function is:

Solve a simpler problem
make a table
make a drawing
use a graph
use guess-and-check
solve an equation
I say that answer would be C:
2 years of lost wages
(45K+45K) = 90K
TOTAL cost of school = 30K
sum of investment
(90K+30K) = 120K
5 years to recover investment
(120K/5yrs) = 24K per year
Salary plus amount required to recover investment
<span>(24K+45K) = 69K
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
