Which function should be used to when evaluating the function at x = 4? HELP PLEASE!!

Answer:
The answer to your question is p(x) = (1/4)x + 2.5
Step-by-step explanation:
To solve this question we must observe the conditions of each function.
-We must use the first function only if the value of x is equal to or lower than 3.
-We must use the second function only of the value of x is higher than 3.
For the value given (4), we notice that it is higher than 3 so we must use the second function.
