Question

Let f(x)= Piecewise [{{-x+2, -2≤x<1} , {x-2, 1≤x≤4}}]

Wolfram Alpha Plot: Plot [Piecewise [{{-x+2, -2≤x<1} , {x-2, 1≤x≤4}}]

Graph y=f(x)
x = -2 through x = 4

Identify the value or values of x where f is discontinuous.

Answer 1

I got x =1 but not sure if I should include -2 and 4 since the lines stop there.

Answer 2

no you don't need to include -2 and 4.....the function just ends at those points but its still continuous at those points
