Determine all numbers at which the function is continuous.
picture provided below

Option C. continuous except x = 5 and x = 9.

Step-by-step explanation:

The given function is

Now we have to check the continuity of the given function

We know if the denominator of a function which is in the form of a fraction is 0 then the given function is not continuous.

If we put x - 5 = 0

x = 5

and x - 9 = 0

x = 9

These are the two values of x for which the function is not defined.

Therefore option C. function is continuous except x = 5 and x = 9

is the correct answer.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
