Determine the value of the zero the equation of the axis of symmetry. the max or min or value and the vertex

(-4,0) and (0,0)

X=-2

Max

(-2,4)

Step-by-step explanation:

The zeros of a function are the x-intercepts. They are found where y=0 on the x-axis. This is where the function crosses the x-axis. They are written as (x,y). Here the zeros in #1 are (-4,0) and (0,0).

The axis of symmetry is the line that divides the parabola in half for a perfect reflection. It is written as x=a. Here it is x=-2. A quadratic has a max or min. This is either the highest or lowest value of the function. Here it is a max at (-2,4). The max or min is also the vertex.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
