4. h(x) = if x * 2 lx-2 c if x = 2 a) Use the precise definition of an infinite limit to demonstrate that lim h(x) = 0o x-2 15 points (See Definition 6 in section 1.7 of the textbook, and the lecture notes for Section 1.7) b) Is there any value for c that would result in h being continuous at the point x = 2? Justify your response. 5 points
