Answer 2

Answer:

TRUE

Step-by-step explanation:

because one -one function is nothing but all the elements in domain must have an distinct image in codomain....in here,

n(A)= 4

n(B)=3

Imagine that,

A={1,2,3,4}

B={5,6,7}

By this we can know that 1 has a image of 5 and 2 has a image of 6 and 3 has a image of 7 but we don't have the image for 4...

Hence there is no one-one function here...
