Use the definition for continuity to determine whether the function continuous at x= 1 and x= 2?

When an equation is given, how would you know if it's continuous or not?

determine the continuity of the function at a.

Determine the continuity of the function at the given points. forx =-1 flx) = -2, for x *-1 at x = -1 and x = 0 6- 5- 4- 3. -1+ O The function f is continuous at neither x =0 nor x=-1. O The function f is continuous at x =0 but not at x = -1. O The function f is continuous at both x = 0 and x=-1. O The function f is continuous at x = -1 but not at x = 0.
