Problem

A function gg is defined on an open interval containing x=4x=4. You are told that lim⁡x→4g(x)=7\displaystyle \lim_{x\to 4} g(x)=7 and that g(4)g(4) is undefined. (a)–(c) use this scenario. a. Part 1: State the three distinct conditions that must all be satisfied for a function to be continuous at a point x=cx=c. Use precise mathematical language. b. Part 2: Explain, with explicit reference to the conditions you stated in part (a), why the information given above is sufficient to conclude that gg is not continuous at x=4x=4. Your explanation should clearly cite which condition(s) fail and why. c. Part 3: Suppose a new function hh is created by defining h(x)=g(x)h(x)=g(x) for x≠4x\ne 4 and h(4)=7h(4)=7. Determine whether hh is continuous at x=4x=4. Justify your conclusion by verifying each condition of continuity at that point.
