Question

Convert [−1,∞) to inequality notation use the variable x.

Answer 1

Answer:

$-1\leq x$

Step-by-step explanation:

We want to convert the interval [-1, ∞) to inequality notation using x as the variable.

The interval [-1, ∞) reads: "All real numbers between -1 and positive infinity."

In other words, it is all numbers greater than or equal to -1 and less than positive infinity.

Therefore:

$-1\leq x$

Note that we do not use "or equal to" for the infinity as we can never really "equal" infinity.
