Question

Write the solution to the given inequality in interval notation.
[2,∞)
(-∞,2)
(2,∞)
(-∞,2]

Answer 1

brackets [ ] are used when the line inequality is equal to the certain point

an open circle on the line graph means its either less than or greater than, not equal to
infinity will always have a parenthesis since you can never reach the exact point of infinity

Answer 2

If we have an expression such as x<4, this means our variable can be any number
smaller than 4 such as − 2, 0, 3, 3.9 or even 3.999999999 as long as it is smaller
than 4. If we have an expression such as\[x \ge-2\] this means our variable can be
any number greater than or equal to −2, such as 5, 0,−1,−1.9999, or even−2.

The value itself we will mark with brackets, either ) or ( for less
than or greater than respectively, and ] or [ for less than or equal to or greater
than or equal to respectively.
