Answer:
yes as x increases by 10, y increased by 2
Answer:

Step-by-step explanation:
we know that
The function of the graph is a vertical parabola open upward
The vertex is a minimum
The equation of a vertical parabola in vertex form is equal to

where
a is a coefficient
(h,k) is the vertex
In this problem
Looking at the graph
The vertex is the point (0,-4)
substitute


To determine the value of "a" take a point in the graph
I take the point (3,5)
substitute the value of x and the value of y and solve for a

therefore
The equation of the quadratic function is
