Quick Exercises:

1.

# Now write a function named adjustRedPercent(picture,adjustmentPercentage) # which takes in the adjustment value as a percentage. E.g. when the # value in adjustmentPercentage is 70, the function should make the # image's red values 70% of their original values. If the adjustmentPercentage # is 140, it should make the image's red values 140% of their original # value. # Hint: There is no need for if-statements. # Note: Assume that adjustmentPercentage will only be 0 or greater. # There is no need to perform error-checking. # Note 2: You can create a corresponding driver in the space below as well.

2.

# Write a driver program that can call these 2 functions and include the 2 functions # as well in your final answer.
