Math Removable, jump or infinite discontinuity?

Question

f(x) {x^2 - 1 if x < 1
f(x){4 - x if x > or = 1

does this equations have removable, jump or infinite discontinuity

Answer 1

Looks like a jump.

At just before X = 1, the first equation goes to 0.
At 1 and just after, the 2nd equation is at 3, heading down.

Answer 2

It has a jump discontinuity at x= 1. The x^2-1 is a parabola that crosses th x-axis at -1 has a minimum of -1 at x= 0 then heads back up anstops ust short o x = 1. then th functi jumps up to (1,3) and then travels downward through the point (4,0).

Answer 3

The left limit of f(x), which is 0, at x=1 is not equal to the right limit which is 3. Therefore, you have a jump disontinuity.
