Translations Part 1

This applet has 5 different functions. Your goals, will be to see how the function f(x) is transformed, when going to f(x)+d. You can move slider "d", and push "Switch Function" to cycle through the 5 available functions. Try it out, and then answer the questions below.
This type of transformation, is called translations. Question 1: Using the word translation, describe the effect of "d", when d>0, when y=f(x) is transformed to y=f(x)+d. Be specific! Question 2: Using the word translation, describe the effect of "d", when d<0, when y=f(x) is transformed to y=f(x)+d. Be specific!
