Answer 1

Step-by-step explanation:

This means all values less than -4 and including -4

It goes from -∞  up to and includes -4

Parentheses for -∞  brackets for -4 since we include it

(-∞, -4]

Answer 2

Answer:

$(-\infty,-4]$

Step-by-step explanation:

So we have the inequality:

$x\leq -4$

This means that our solution is all numbers less than or equal to -4. Therefore, in interval notation, this is:

$(-\infty,-4]$

This represents all the numbers from negative infinity up until -4. This is equivalent to the inequality.
