Question

Write the solution to the given inequality in interval notation.

[-3,∞)
(-∞,-3)
(-3,∞)
(-∞,-3]

Answer 1

[-3, infinity)
It is greater than or equal to -3 and goes on to infinity

Answer 2

The solution to the given inequality in interval notation is:

[-3,∞)

Explanation:

The solution of the given inequality is the set of all the possible x values.

By looking at the graph which is a number line such that the shaded region is to the right of -3 and the arrow of solution goes to infinity and also there is a closed circle at -3.

This means that -3 is included in the solution set.

This means that the solution is all the real values which are greater than or equal to -3.

i.e. The solution is: x ≥ -3

i.e. [-3,∞)
