3. 1.7 Transformations Parent Function – simplest form of a type (or family) of graphs Using a parent function you can transform the graph to create other graphs of the same family.

4. Parent Functions

5. Order of Operations

6. Translation

9. Translation

12. Practice 1.Graph 2.Graph 3. Graph y = |x+2| + 2

15. y = |x+2| + 2

16. Reflection When the parent function is multiplied by -1 the result, -f(x) is a reflection across the x axis The figures flips over the line of reflection

17. A graph can be reflected across any line including the x-axis, y-axis, origin, y=x, etc.

20. Practice 1.Graph y= -|x-1|-2

21. Dilation A dilation shrinks or enlarges a graph proportionally. When a function is multiplied by a nonzero number the slope changes which stretches or compresses the graph. Coefficients over 1 cause the graph to be stretched vertically. Coefficients between 0 and 1 cause the graph to be compressed vertically.

22. y=3|x| y= ½ |x| y=|x|

23. Horizontal dilation When the variable is multiplied by a nonzero coefficient, the graph is stretched or compressed horizontally.

24. y=x y=½x
