The expression would be m-2
Given:
The vertex of a quadratic function is (4,-7).
To find:
The equation of the quadratic function.
Solution:
The vertex form of a quadratic function is:
...(i)
Where a is a constant and (h,k) is vertex.
The vertex is at point (4,-7).
Putting h=4 and k=-7 in (i), we get


The required equation of the quadratic function is
where, a is a constant.
Putting a=1, we get

![[\because (a-b)^2=a^2-2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a-b%29%5E2%3Da%5E2-2ab%2Bb%5E2%5D)
Therefore, the required quadratic function is
.
Answer:
C
Step-by-step explanation:
Solve the quadratic in answer choice C using the quadratic formula:
.
Here a=1, b=2, and c=17.
Substitute and you'll have:
It would be the last option, (5, -4)
The cost of each turkey, if each is a smudge that represents some unreadable digit is $0.94
<h3>Cost of each turkey</h3><h3 />
- Total number of turkey bought = 72
- Total cost = $67.9
Cost of each turkey = Total cost / Total number of turkey bought
= 67.9 / 72
= 0.943055555555555
Approximately,
Cost of each turkey = $0.94
Therefore, the cost of each turkey, if each is a smudge that represents some unreadable digit is $0.94
