Step-by-step explanation:
Given that :
Estimated number of voters in favor of additional restriction = 43%
Margin of Error = ±4%
Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction:
Minimum percentage of voters = 4% lesser than the estimated number of voters
Maximum percentage of voters = 4% greater than the estimated number of voters
Let number of voters = v
|v - 43%| = ±4%
v = - 4% + 43% = 39% = minimum percentage
v = +4% + 43% = 47% = maximum percentage
39% ≤ v ≤ 47%
It crosses the x axis when y = 0.
so we need to solve x^2 - x - 2 = 0.
This is done as follows:
x^2-x-2=0
(x-2)(x+1) = 0
Therefore x = 2 or x = -1.
So the two coordinates are (2,0) and (-1,0) the answer is A
