One one onto Let X1,X2 €R s.t. F(X1)=f(X2) X1^3=X2^3 X1=X2 Hence f is one one Let x^3=y x=y^1/3 For each value of y there exist x € R Hence function is onto.

Yes, it is an equivalence relation . Because For Reflexive a=b. So (a,a)€R And for symmetric (a,b)€R, a=b Then (b,a) €R For transitive (a,b)€R a=b -1 (b,c)€R b=c -2 From eq 1 and 2 a=c Then (a,c)€R So it is an equivalence relation

Determinant of skew symmetric matrix is always zero. For Example = Let's take a general skew symmetric matrix |0 b c| |-b 0 e| |-c - e. 0| 0(a+e²)-b(0-b)-(-ec)+c(be-0) =0-bec+cbe=0 Therefore determinant of skew symmetric matrix is always zero.

Given A={1,2,3_____,13,14} R={(x, y) :3x-y=0} R={(1,3),(2,6),(3,9),(4,12)} 1)Since 1€A but (1,1)does not belong to R Therefore, R is not reflexive 2)since (1,3)€R but (3,1) does not belong to R Therefore R is not symmetric 3) since (1,3)&(3,9)€R but (1,9) does not belong to R Therefore R is not transitive
