Question

I give medals and fans, please help !

The graph of a piecewise function is shown below. The function is discontinuous at x = 0. What is the y value when x = 0?

y = 1
y = 2
y = 0
y is undefined

Answer 1

the graph is poorly drawn, the answer is either y=2 or y is undefined. We would need to plug x = 0 in the actual function to know if it the value exists.

I would go with y = 2 instead of y is undefined because the latter requires more complex functions to look the way it does.

Answer 2

Yeah the graph confused made me a little confused on this question. Thank you!

Answer 3

the graph needs to have some form of "dot" to determine this.
