Q15 of 29 Page 1

Using properties of determinants, prove that:


C1→aC1



C1→C1 + bC2 + cC3



Taking a2+b2+c2 common from C1 we get,



R2→R2 - R1


R3→R3 - R1







= (a2+b2+c2)(a+b+c)= R.H.S

Prove that the function f: [0, ∞) → R given by

f(x) = 9x2 + 6x – 5 is not invertible. Modify the codomain of the function f to make it invertible, and hence find f-1.


OR


Check whether the relation R in the set R of real numbers, defined by R = {(a, b) : 1 + ab > 0}, is reflexive, symmetric or transitive.
