<u>Given</u>:
Given that the graph of the quadratic function.
We need to determine the value of a in the function's equation.
<u>Value of a:</u>
The value of a can be determined using the formula,

where (h,k) is the vertex and a is a constant.
From the graph, it is obvious, that the vertex of the parabola is (0,9).
Thus, substituting the vertex (h,k) = (0,9) in the above formula, we get;

-------- (1)
Let us substitute any one of the coordinate that the graph passes through to determine the value of a.
Let us substitute the point (3,0) in the equation (1), we have;




Thus, the value of a is -1.
Hence, Option B is the correct answer.

Answer:
The father is 59
Step-by-step explanation:
lets say each of the kids are twelve
30*5=150-36=114=59+55
30*5+ 150 the age of everyone in the family added together
12*3= 36 the age of all the kids
150-36=114 the age of the adults added together
we know the mother is 4 years younger than the father so to state off you can take 114 and divide it by two to get what half of it is then take take numbers that are four apart to find the ages that add up to 114.
I think we need to divide some numbers there
