Write the equation of the quadratic equation function i standard form represented by the graph

Step-by-step explanation:

we know that

The quadratic equation in standard form is equal to

In this problem we have

the vertex is equal to the point

The zeros of the function are the points and

The graph of the figure is a vertical parabola open upward

the equation of a vertical parabola in vertex form is equal to

where (h,k) is the vertex of the parabola

substitute

with the point find the value of a

the equation in vertex form is equal to

Convert to standard form

equate to zero

my answer is$ 12

step-by-step explanation:

because 15 -2=12
