Answer:

60

Step-by-step explanation:

The quadratic function tells me that the graph has a vertice at (-40, 60).

So the minimum number of mango yield per year is 60.

Howevery, i believe that there is a mistake in the question;

The quadratic function should be [tex]y = (x-40)^2 +60[/tex]

Because we cannot have negative number of mango tree.
