“Parent” functions Linear

Do you think they look alike?

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

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

“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? ____________________________

“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?__________________________

“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? _____________________
