Answer 1

Answer:

Step-by-step explanation:

Given that

$f(x)=3x^{2} +5$

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.

Answer 2

Answer:

B

Step-by-step explanation:

Hence the inverse of f(x) which is f⁻¹(x) =√[(x-5)/3] is NOT a function

Only the inverse is a function.WRONG

Neither the equation nor its inverse is a function.WRONG

Only the equation is a function.RIGHT

Both the equation and its inverse are functions.WRONG
