Answer:

Step-by-step explanation:
The h and k are the points of the vertex. The h is the one inside the absolute value bars. The k is on the outside. The h has to be the opposite sign from what is on the graph. For example, if the number on the the graph is -1, the number in the <em>equation</em> will have to be a positive 1. The number on the outside stays the same. If the number on the the graph is +1, the number in the <em>equation</em> will also be a positive 1.
The answer is $328,000. Since the investment is $82,000 every seven years, and there is 28 years. If you divide 28 by 7 you get 4. Then you multiply 82,000 by 4 to get your answer : $328,000.
3*3^2+2*10^2-15=212
The answer is 212
i am only here for points but this is very easy
So,
The coefficient, which in this case is the numerical coefficient, is 7.
