2.  You should be able to tell when a graph is shifted, reflected, stretched or shrunk. You should also be able identify transformations from an equation.

3. translates the graph c units up The +3 moves it up 3.

4. translates the graph c units down The -3 shifts it down 3.

5.  reflects the graph across the x-axis › (flips up side down)  ex: The negative makes it reflect over the x-axis

6. reflects the graph across the y-axis (flips sideways) The negative on the inside reflects it across the y-axis.

7. Notice: is much narrower than Vertical stretch (multiply by a number greater than one and the graph is stretched “taller” and “narrower”)

8. To make it shrink multiply by a number less than one, like a fraction or decimal, and the graph is shrunk “shorter” and “wider.” Notice: is much wider than

9. What does the negative out front do? What does the 3 do to the graph? What does the 7 do to the graph? Reflect over the x-axis stretch Shifts it 7 units up Click on the questions to check your answers.
