Question
Let f be the function defined by f(x)= \ array ll x^ 2 -1 x^ 2 -2|x-1|-1 , & x 1 \\ 1 / 2, & x=1 array .
Let f be the function defined by f(x)= \ array ll x^ 2 -1 x^ 2 -2|x-1|-1 , & x 1 \\ 1 / 2, & x=1 array .
D. The function is not continuous at x=1
For x 1, f(x)= x^ 2 -1 x^ 2 -2 x+1 = x+1 x-1 _ x 1^ + f(x)= The function is not continuous at x =1.
