Sir,
It would be highly helpful if you could explain why is the set R in the Q5 is not a bijective function? Please refer to the screenshots above.
Thank you
Your Sincerely

a function is bijective if it is both injective and surjective. If you see the practice assignment solution, you will see the condition of surjectivity is not fullfilled. R as a function is not defined for all values on the x-
axis, and Y is not the set of all values on the y-axis,
