Answer:
Step-by-step explanation:
We want to convert the interval [-1, ∞) to inequality notation using <em>x</em> as the variable.

In other words, it is all numbers greater than or equal to -1 and less than positive infinity.
Therefore:
Note that we do not use "or equal to" for the infinity as we can never really "equal" infinity.
