Answer: Option a.
Domain: (-∞, ∞)
Range: (-∞, ∞)
Step-by-step explanation:
We have the function 
Note that f(x) is the sum of two continuous functions
and 
The domain and range of h(x) are all real numbers
The domain of g(x) is all real numbers. The range of g(x) is [-1, 1]
Then the domain of
will be <u>the intersection</u> of the domains of the function
and the function
.
Therefore <u>the domain of f(x) are all real numbers</u>. x ∈ (-∞, ∞)
The range of f(x) will be equal to<u> the union</u> of the range of g(x) and h(x)
Therefore <u>the range will be all real numbers f(x) </u>∈ (-∞, ∞)
Answer:
To perpendicular bisector of line segment WX. There are following steps:
1) Draw arcs or circles from points A and B on the both sides of WX.
2) Name the intersection points as W and X.
3) Use the straightedge to draw a line through points W and X.
4) Name the point as O
hence we have construct perpendicular bisector AB of WX which bisects at O.
