Question

Can someone help me graph the piecewise function below?

Answer 1

For all x < 1, f(x) or y = 3 (this is a horizontal line, parallel to the x-axis)
For all x >= 1, f(x) or y = x (this is a 45 degree straight line)

Since the point x = 1 is included in the second definition but not the first, you should put an open circle on the first graph at x = 1 and a closed circle on the second graph at x = 1.

Answer 2

Thank you so much for explaining this!! I appreciate it. :-)

Answer 3

You are welcome.
