 Sketch the graph of the piecewise defined function

f(x) = 1−x if x ≤ 1,

1 if x > 1

 

b) and evaluate f(f(−3)).

Ok part B.

F(f(-3)) is just f("what f(-3) is").

Well we know that 1 is greater than -3 so we use the first equation

f(-3) is 1- -3 or 4. 

f(f(-3)) is f(4).

4 is greater than 1 so now we use the second equation. 

f(4) is just 1. 

So the answer is just 1. 

Hope this helps.
