How would an increase in each of the following affect the consumption function

I had that same exact question on my test, and here are the answers to the A B C D

a. negative, high tax, low consumption.

b. negative, high interest rate, low consumption.

c. positive, high confidence, high consumption.

The saving function = Income - Consumption. You do the math. High consumption, low saving.
