How do you graph #-40 \le y < 60# on a number line?

Answer 1

see below :)

ok
so you have your number line
its a nice lil line

for the ones with a less/greater than or equal to (< or > with the line under it) you put a solid dot on the value
so like in yours you'd put a filled in dot on -40

and for the ones that are just < or > (without underline) you put a dot THAT IS NOT FILLED IN (important).
so in yours itd be an unfilled dot on 60

and now we look a little more closely at the sign
what this problem essentially says is y is greater than or equal to -40, but smaller than 60

so you draw a nice dark line spanning from -40 to 60

To graph the inequality -40 ≤ y < 60 on a number line, you would draw a solid dot at -40 and an open circle at 60, indicating that 60 is not included in the solution set. Then, you would draw a solid line between these two points to represent all the values of y that satisfy the inequality.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
