<h2>Answer:</h2>

The function which are continuous are:

                Function 2 and Function 3.  (graphs attached)

<h2>Step-by-step explanation:</h2>

We know that a function is said to be a continuous function if the limit at each of the points exist and is equal to the value of the function at that point.

Also, in the graph of a continuous function there is no break i.e. the graph is connected at all the points.

  • Here we observe that in the first graph there is a break close to x=0.

      and hence the function is not continuous.

  • The graph of second function is continuous since the limit exist at all the points.
  • The graph of the third function is again continuous.
  • But the graph of the fourth function is not continuous since, the left as well as right hand limit at  x= -1 is not equal.

This means that the limit at x= -1 does not exist and hence the function is not continuous.

>>1st one- at X=0 Y=DNE so the function is not continious.
>>2nd one- there is Y value for every X so the function is continious.
>>3rd one- there is Y value for every X so the function is continious.
>>4th one- f(-1)=1 does not equal the limit of f(x).


because the limit as X aprroaches from the left and from ther right is different.

The memory card on melcher did it's camera can hold about 430 pictures. Melcher used 18% of the memory card while taking picture
Korolek [52]
Just cross multiply to find 18% of 430
18/100 = x/430
430 X 18 = 7740
7740 = 100x
7740/100 = 77.4
so Melcher took about 77 photos.

Solve by factoring.<br><br> m^2+6m+5=0
alina1380 [7]

Answer:

<u>-1 and -5</u>

Step-by-step explanation:

m^2 + 6m + 5 = 0 is factored to: (m + 1)(m + 5) = 0.

The zero product property states that one of the represented parenthesis must equal zero to satisfy the right side of the equation.

(m + 1) = 0

(-1 + 1) = 0

This means that one of the values for m is -1.

(m + 5) = 0

(-5 + 5) = 0

This means that one of the values for m is -5.

<u>Moreover, the value of m by factoring is -1 and -5</u>
