Answer the following questions using the above information. |
A) Neither Surjective nor Injective
B) Surjective
C) Injective
D) Bijective
Correct Answer: A
Solution :
\[y={{x}^{2}}\] From \[x=-1,\,\,y=1\] \[x=1,\,\,y=1\] \[\therefore \,\,\,f\left( x \right)\] is not injective For \[y=2,\,\,{{x}^{2}}=2\] Also f(x) is not onto.You need to login to perform this action.
