Answer:
Step-by-step explanation:
Given that
We find that this is a parabola symmetric about x=0 or y axis.
For each x, we have a unique y but for each y we have two x's
So inverse cannot be a function. Option 1 is wrong
b) The given equation is a function, because each x has a unique image in y.
c) The inverse cannot be a function as for each y, there are two different x's
d) Neither the equation nor its inverse is a function is wrong because equation is a function.
