By analyzing the graph of the function, we will see that:

  • a) DNE
  • b) 3
  • c) -1
  • d) 3
  • e) DNE
  • f) 2

<h3>How to get the limits of the given function?</h3>

Remember that when we take a limit to a given value, we approach to that value by two directions (from above and below) and see at which value the function approaches.

So, for the first limit we have:

x ⇒ -2

As you can see, if we approach from below the function tends to 4, while if we approach from above, the function tends to -1, which means that this limit does not exist. DNE.

x ⇒ 0

The function is continuous here, so the limit is equal to the value of the function in that point, which is 3

x ⇒ 2

If we approach from above and below we get the same number, which is -1, so the limit is equal to -1.

x = 2

Now we are directly evaluating the function in x = 2, and we can see that there is a jump such that f(2) = 3

x ⇒ 4

Here we have two asymptotes, one goes to infinity and the other to negative infinity, so this limit does not exist.

x ⇒ ∞

So we can't see how the function behaves for large values of x, so there is no way to answer this exactly.

If we suppose that the function does not change, we can see that we have a rational function in the right side of the image, so we can expect that as x tends to infinity, the function will tend asymptotically to 2.

Why 2?

Because the denominator becomes zero when x = 4, then when x = 5 the denominator is equal to 1.

At that point, the function is equal to 3, so the function is something like:

y = 1/(x - 4) + 2

Answers:
(2) Option (B) 4
(3) The answer is: +1

Explanations:
(2) The plus sign in the limit indicates that it is the right hand limit. So we have to approach to 2 from the right side of the graph. When we do that, we see the value of y = +4. Hence the correct option is (B) 4

NOTE: Although the question seems complex because there is slope involved but in this particular case, the examiner is concerned about the right hand limit.

(3) The minus sign in the limit indicates that it is the left hand limit. So we have to approach to 3 from the left side of the graph. When we do that, we see the value of y = +1. Hence the correct answer is +1.

Your city is represented in a coordinate plane where each unit represents 1 kilometer. The library is at (1, −2), the post offic
Rasek [7]

Answer:

The answer to your question is 10.7 units

Step-by-step explanation:

To solve this problem, just calculate the distance from the House to the Library, then the distance from the Library to the Post office and finally to the Post office to the house.

I hope this helps! Also, pls mark me as the brainliest!

AlSO IF YOU WANT THE STEP BY STEP EQUATION IT IS--->

dHL = \sqrt{(-2 + 3)^{2} + (-2 - 2)^{2}}

dHL = \sqrt{(1)^{2}+ (-4)^{2}}

dHL = \sqrt{17} = 4.1

dLP = \sqrt{(-2 -2)^{2} + (-2-2)^{2}}

dLP = \sqrt{(-4)^{2} + (-4)^{2}}

dLP = \sqrt{32} = 5.7

dPH = \sqrt{(2 + 3)^{2}+ (2 - 2)^{2}}

dPH = \sqrt{(5)^{2}+ (0)^{2}}

dPH = \sqrt{25}

dPH = 5

Minimum distance = 4.1 + 5.7 + 5

Minimum distance = 10.7

For number 6 can anyone tell me the answer
slamgirl [31]
The perimeter of MATH is 4w + 6 and the perimeter of GEOM is 6w - 8. the perimeters are the same so set them equal,
  4w + 6 = 6w - 8... use inverse to get all like terms on opposite sides
-4w + 8 = -4w + 8
        14 = 2w... divide both side by 2 to get w alone
       ÷2  = ÷2
          7 = w
so B. 7 is the answer
