Question

Using complete sentences, explain how to graph the following piecewise function:

y = x^2 if x < 1
y = 3x if x≥1

Answer 1

graph \(y=x^2\) up until \((1,1)\)
put a nice open circle at that point , then go to \((1,3)\) put a big closed circle there and then graph \(y=3x\) from that point on
