Answer:
Assume x is directly proportional to y :
when y is 9, x is 2:
substitute to find value of k :
Therefore, equation is:

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 .
