2.7.59 Function Properties

Condition: Given the function: \ [f (x) = \ left \ {\ begin {array} {c} \ frac {\ sin 2 x} {x}}} \ frac {n} {x}-\ frac {k \ squrt {1+2+2+2+2+2 x}} {x^{2}}, x <0 \\ -1, \ quad x = 0 \\ m -x^{(1+2 x)^{\ frac {1}},}, x> 0 \ end {Array} \ Right. \] At what values of the parameters \ (p, n, k, m \) is the function continuous?
