Question

Math help!!!?
How do I solve this problem? Can anyone explain?

Answer 1

First you find what fits the qualifications of the function.
Part 1: f(0) fits with x<= 1, so you simply plug in 0 for that function.
(0)^2 = 1

Part 2: f(x) = 1 
That means there is a horizontal straight line intersecting (0,1)
