Answer:
rational
Step-by-step explanation:
We can solve this problem by seeing at which part both of the parts of the graphs of the function are discontinued. Both of the parts of the graph of the function are discontinued at -2, so we will have to find a function that has a value that is undefined for x = -2. We can do this using the denominator of the fraction that's in each of the functions. The function where x = -2 will cause it to be undefined is the third one, so the answer to this question is C.,
f (x) =
+5.

Answer:
D) I and II only
Step-by-step explanation:
C=
5/9(F−32)
If F goes up 1 degree (33 degrees)
C=
5/9(33−32)
C = 5/9 *1 = 5/9
So the first 1 is true
If C goes up 1 degree
1=
5/9(F−32)
Multiply each side by 9/5
9/5 = 9/5 * 5/9 (F-32)
9/5 = (F-32)
1.8 = F-32
Add 32 to each side
33.8 =F
The change from 33.8 to 32 is 1.8 degrees F so 2 is true
If F goes up 5/9 degree
C=
5/9(5/9)
C = 25/49
False
