1. Given the function definition below, which of the following are NOT legal/appropriate
calls to the function.  Explain.

def add_one(value):
    return value+1


a. add_one(10)
b. add_one()
c. add_one
d. add_one(-1)
e. add_one(2, 3)
f. add_one(16.1)
g. add_one("cs150 is great")

2. The program below is supposed to calculate the length of the hypotenuse of a right
triangle with sides 3 and 4 and print out the answer.  However, the program has three
errors in it: one syntax and two when it runs relating to type.  What are the three
errors?  Try and figure it out WITHOUT trying to run the program.

# take the sqrt of a number
def my_sqrt(x):
    return x**(1//2)

# calculate the length of the hypotenuse of a right
# triangle
def hypotenuse_length(a, b)
    sum = a**2 + b**2
    return my_sqrt(sum)

print("If a is 3 and b is 4 then hypotenuse is " + hypotenuse_length(3,4))

3. What is wrong with the following function:

def triangle_area(base, height):
    return base*height/2.0
    print("Base is: " + str(base))
