Question

Write the solution set in interval notation.

a. (-[infinity], -1) U (1, [infinity])
b. (-[infinity], -1/2) U (1/2, [infinity])
c. (-[infinity], -2) U (2, [infinity])
d. (-[infinity], -2/5) U (2/5, [infinity])

Answer 1

The solution set in interval notation for the given expressions are: a. (-∞, -1) U (1, ∞), b. (-∞, -1/2) U (1/2, ∞), c. (-∞, -2) U (2, ∞), d. (-∞, -2/5) U (2/5, ∞)

Step-by-step explanation:

The solution set for interval notation can be written as:

a. (-∞, -1) U (1, ∞)

b. (-∞, -1/2) U (1/2, ∞)

c. (-∞, -2) U (2, ∞)

d. (-∞, -2/5) U (2/5, ∞)
