let
f(x) =1 + 2π₯, π₯ β€ 0
=3π₯ β 2,0 < π₯ β€ 1
= 2π₯ ΰ¬Ά β 1, π₯ > 1
i) Check whether f is discontinuous. If yes, find where? ii) Give a rough sketch of the graph of f.
i)
The function f(x)f(x)f(x) has an jump discontinuity at x=0.x=0.x=0.
The function f(x)f(x)f(x) is continuous at x=1.x=1.x=1.
The function f(x)f(x)f(x) is discontinuous at x=0.x=0.x=0.
ii)
