Question

Write the solution to the given inequality in interval notation.

Answer 1

It's the first choice because the -4 has a closed dot over it. That signifies using a bracket instead of a parenthesis. Infinity doesn't ever end so that will always be parenthesis, no matter if it's negative infinity or positive infinity.

Answer 2

The solution to the given inequality in interval notation is:

[-4,∞)

Explanation:

By looking at the graph we observe that the solution to the graph is the set of all the values which are greater than -4 because the shading is to the right of -4 and there is a closed circle at -4 this means that -4 is included in the solution set.

Hence, the solution set is: x ≥ -4

which in interval notation is given by: [-4,∞)
