please help me with these problems, i'm stuck on them (graphs for the one asking to evaluate each quantity are provided)

\f\f(1 point) f(x) g(x) The graphs of f(x) and g(x) are given above. Use them to evaluate each quantity below. Write DNE if the limit or value does not exist (or if it's infinity). DNE 1. lim [f(g(x))] x-1 DNE 2. lim [f(x)/g(x)] x-1 DNE 3. f(3)/g(3) DNE 4. lim [f(x) + g(x)] DNE 5. lim [f(x) + g(x)] x-1+ DNE 6. lim [f(x)g(x)] x-+3+ DNE 7. lim [f(g(x))] x-3 DNE B. lim [f(x) + g(x)] x-3 DNE 9. lim [f(g(x))] DNE 10. f(1)/g(1) DNE 11. lim [f(g(x))] DNE 12. lim [f(x)/g(x)] x-1+\f(1 point) A function f(x) is said to have a jump discontinuity at x = a if: 1. lim f(x) exists. 2. lim f(x) exists. 3. The left and right limits are not equal. (+4x+2 ifx
