Homework Statement Can someone tell me why and why not following functions are Continous and Differentiable. I am also providing the answer but can some help me understand.. thanks 1) f(x) = x^(2/3) -1 on [-8,8] answer: function is continuous but not differentiable on -8. Is that...

may be I don't understand the problem to begin with.. can you explain. thanks

double checked it. the have it right. any ideas?

if 4-x^2 < f(x) < 4 + x^2 for x in [-1,1] then what's lim as x goes to zero of f(x) ... this setup looks like epsilon form .. not sure how to interpret this guy...
