I Think the answer is a& b
This is a bit harder. I suggest getting the Domain and Range for the function of x.
If any of these answers have, an infinite domain and (3, infinite) range. That will be your answer.
Your answer is B.
f(x) = 2x²+3 has the same domain and range as x²+3
27%=27/100
so 27/100=81/x
27x=8100 divide by 27
x=300
that the answer
For this one your answer is -309
