Answer:
The operation of 6*x only executes if x is greater or equal to 0, since x=-10 and -10 is less than 0, the operation does not execute. For this reason, the value of y using this code is None.
Explanation:
In python a function is defined with the syntaxis:
def function(x):
the operation to execute (x)
value to return
In this case, the function is foo and the parameter is x:
def foo(x):
if x>= 0:
return 6*x
The code starts by assigning a value to x. Then, the code asks if the value of x is grater or equal to 0, if this condition is meet, then the code returns the value of 6 times x, if not, then the code does not return a value. In this case, x is -10 and this value is not grater or equal to 0. Given that the condition is not met, then the code stops executing and the value of y is none.
