Answer:
The correct answer to this problem is 15.
Step-by-step explanation:
To solve this problem, we first need to evaluate p(12) and p(-3). To do this, we simply plug in the number in parentheses into each occurrence of x in the equation given. This is modeled below.
p(12)= 12+6 = 18
p(-3)= -3+6=3
Now, we must use these values we have found in our other expression.
p(12)-p(-3)
18-3
15
Therefore, your answer is 15.
Hope this helps!
