Answer:
x ∈ (-∞ , -2) ∪ (1, 3)
Step-by-step explanation:
The expression is already factored. Note that for the polynomial that appears in the numerator there are 2 roots:
For the polynomial that appears in the denominator there is 1 root:
Note that does not belong to the domain of f(x) because it zeroes the denominator of the function and the division between zero is not defined.
With these three roots we do the study of signs to find out when

We can find the distance between two points by using distance formula,
Here,
x₁ = -3
x₂ = 5
y₁ = -2
y₂ = 2
Therefore,
Hence the √80 = 8.94 approx is the distance between the two points (-3,-2) and (5,2).
Answer:
<u>Part A</u>
Two lines can be parallel or intersect. There is no solution when the lines are parallel, infinite solutions when lines overlap.
- Since A and B intersect, there is <u>one</u> solution.
<u>Part B</u>
The intersection of A and B is a point with coordinates:
