Answer: YES, IVT 14. (8 points) Let f(x) = { 2x + 2 if x ? -1 x^2 if -1 < x < 1 2x - 1 if x ? 1 a. Graph and find the numbers at which f is discontinuous. (Using calculus justify your answer.) 2(-1)+2=0 2(1)-1=1 discontinuous at 0 b. At which of these numbers is f continuous from the right, left or neither? f continuous at 1 from right at -1 from left neither at 0 b) Answer: 1,-1,0

Find the numbers at which f is discontinuous. At which of these numbers is f continuous from the right; from the left; or neither x + 2 if x < 0 43. f(x) = e' if 0 <x<1 2 - X if x > 1
Zhumagali S.
Find the numbers at which the function $$f(x)=\left\{\begin{array}{ll} x+2 & \text { if } x<0 \\ e^{x} & \text { if } 0 \leqslant x \leqslant 1 \\ 2-x & \text { if } x>1 \end{array}\right.$$ is discontinuous. At which of these points is $f$ continuous from the right, from the left, or neither? Sketch the graph of $f.$
