To start off, the wording of this question is pretty technical. Let's reword the question to make it a bit easier to understand.
From the open interval from -2 to 5 (meaning between but not including those integers), list every integer for x at which x approaches a defined y point on the curve, regardless of whether it actually takes that y value at that point.
Let's start with the first eligible integer, -1.
The limit, from both sides, as x approaches -1 is y=-1.
However, y = -2 at this point.
At 0, x continuous and defined on the curve where you would expect it, and therefore the limit at x=0 is its y value at that point, 0.
x=1 is not eligible, because its left-side limit (when approaching from the left) and right-side limit (when approaching from the right), are distinct.
x=2 has a clear defined limit. It is continuous and defined at that point. The limit looks to be around y= 1.8
x=3 does not feature a clearly defined, finite value, since the limit at x=3 is
-∞
x=4, like x=0 and x=2, has a clear and finite limit, since it is continuous at that point.
Answers are x=-1, x=0, x=2, and x=4
or
{-1, 0, 2, 4}
There you go. Let me know if you have any questions!
X= 25.65 + 16.5 - 12.45
X= 29.70
Answer:
200 pairs of sandals
Step-by-step explanation:
Represent the sandals with x and the running shoes with y.
In a typical month:
In April
Required
The number of sandals in a typical month
<u>In a typical month:</u>
If 1 sandal costs 2.50, then x costs 2.50x
If 1 running shoe costs 4, then y costs 4y
The total is:
<u>In April:</u>
If 1 sandal costs 2.50, then 2x costs 5x ---- <em>we used 2x because the pairs is doubled </em>
If 1 running shoe costs 4, then y costs 4y
The total is:
The equations are:
Subtract
