Answer:
your answer is incorrect. The correct answer is and
.
Step-by-step explanation:
If a quadratic function is and a>0, then minimum value of the function at point .
The given function is
Here, a=1, b=b and c=182. So.
Put in the given function to find the minimum value of the function.
We know that minimum value is 13. So,
Taking square root on both sides.
The value of b is 26.
So, the given function is
Now, add and subtract square of half of coefficient of x.
On comparing with , we get
Therefore, your answer is incorrect.
