What quadratic function does the graph represent?

,

Step-by-step explanation:

The function of the graph can be written in the vertex form as

, where V(h,k)=V(2,4) is the vertex of the quadratic function.

We substitute the value to obtain;

,

The point (5,1) lies on the graph so we use it to determine the value of a.

,

,

,

The required equation is

,

the one that has a slope of 1/2 and is positive.
