Use the definition of continuity and the properties of limits to show that the function is continuous at the given number a. f(x)-(x + 2x3)4, a =-1 4 lim-1 f(x) = xlir끄1 ( | x + 2 x 3 4 limx+ lim x3 81 f(-1)81 Your answer cannot be understood or graded. More Information Thus, by the definition of continuity, f is continuous at a--1.
