Answer:
a
Step-by-step explanation:
(a)The domain of the function is,
(b)The given function is discontinuous at x=0.
<h3>What is the domain and range of a function?</h3>
Domain is the set of values for which the given function is defined. Range is the set of all values which the given function can output.
The standard function is;

The domain of the given function is found as;

The domain of the function is,

To find the function is continuous or not, we have to find the continuity;

At x= 0 the function is undefined. So that the function is discontinuous at x=0.
Hence, The domain of the function is,
and the function is discontinuous at x=0.

#SPJ1
Answer:
A
Step-by-step explanation:
For this problem, all you need to do is find the three #'s that add up to 156.
So, lets look at the answers and add them up.
A. 50, 52, 54
50 + 52 + 54 = 156
B. 51,52,53
51 + 52 + 53 = 156
C. 49,50,51
49 + 50 + 51 = 150
D. 49,51,53
49 + 51 + 53 = 153
We get the answers (50,52,54) and (51,52,53)
Now, consecutive numbers are numbers that in order, like 1,2,3.
Therefore, the answer is (51,52,53)
It is 2.56 its really ovbious
