For questions 5-8, consider the following code:

def mystery(a, b = 8, c = -6):
return 2 * b + a + 3 * c

#MAIN
x = int(input("First value: "))
y = int(input("Second value: "))
z = int(input("Third value: "))
Suppose we add the following line of code to our program:

print(mystery(x, y, z))
What is output when the user enters 4, 3, and 7?
