Write the equation of the function whose graph is shown.

Step-by-step explanation:

Given : from the graph vertex is (5,3)

Also graph passes through point (8,12)

We use vertex form of quadratic equation

General vertex form is

vertex is (5,3)

h= 5 and k =3

So equation becomes

Now we need to find out 'a'

We use (8,12) to find out 'a'

Plug in x=8 and y = 12

12= 9a + 3

subtract 3 on both sides

9 = 9a

divide both sides by 9

so a=1

Final equation is
