The roots of an equation are simply the x-intercepts of the equation.
See below for the proof that 
has at least two real roots
The equation is given as:
There are several ways to show that an equation has real roots, one of these ways is by using graphs.
See attachment for the graph of
Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)
From the attached graph, we can see that crosses the x-axis at approximately <em>-2000 and 2000 </em>between the domain -2500 and 2500
This means that has at least two real roots

Sample size is an act of picking the number of observations to include in a statistical sample
Answer:
y = x -3
Step-by-step explanation:
From the graph we see the line goes from point (0, -3) to point ( 3, 0), so we can find the slope as m= rise ( go up 3) / run ( go to the right 3) = 3/ 3 = 1
From the graph we can also see the y-intercept ( where the line intersects the y axis is at b = -3
The general equation of the line is y= mx+ b
Our line's equation is y = x -3, because m=1 and b= -3
