1. “Parent” functions
Linear

2. Do you think they look alike?

3. Parent functions in math…
Parent function- the “original” graph; usually the simplest one in the “family”
“baby function”-similar to the parent but not an exact copy

4. Parent for linear functions:
f(x)= x +0
We usually do not write the zero.

5. “Parent” “Baby” What is the y intercept?______
Graph: f(x) = x + 1
Graph: f(x) = x
What is the y intercept?______
Is the slope positive or negative?_________
What is the y intercept?
____________
How is f(x)=x+1 different from f(x)=x?_________________________
How is it the same?
____________________________

6. “Parent” “Baby” How is f(x)=x – 3 different from
Graph: f(x) = x
Graph: f(x) = x – 3
How is f(x)=x – 3 different from
f(x)= x ?___________________
How is it the same?__________________________

7. “Parent” “Baby” Graph: f(x) =2x + 3 Graph: f(x) = x
How is f(x)= 2x + 3 different from f(x) = x?________________
_______________________________________________________
How is it the same? _____________________
