Answer:
10, 11 , 16, 18 &19
Step-by-step explanation:
Given:
Consider the quadratic function is

With given vertex (5,8) and given point (1,3).
To find:
The equation of quadratic function.
Solution:
The quadratic function is
...(i)
Where, (h,k) is the vertex and a is a constant.
Vertex is (5,8). So,


Putting
in (i), we get
...(ii)
The given point is (1,3). Putting x=1 and y=3 in (ii), we get




Putting
in (ii), we get

Therefore, the required quadratic function is
.
Answer:
