<u>Corrected Question</u>
Is the function given by:
continuous at x=4? Why or why not? Choose the correct answer below.
Answer:
(D) Yes, f(x) is continuous at x = 4 because 
Step-by-step explanation:
Given the function:

A function to be continuous at some value c in its domain if the following condition holds:
- f(c) exists and is defined.
exists.
At x=4
Therefore: 
By the above, the function satisfies the condition for continuity.
The correct option is D.
D. When you do the math, the results to everything should be t=9. D is the only outlier. Therefore, D is the answer in this case.
3x+20=5x+12
-3x -3x
20= 2x +12
-12 -12
8=2x
Divide both sides by two
4=x
It will take four days (this is how to solve algebraically)
