Answer: A
Step-by-step explanation:
Letting
,

Also, the domain of an inverse is the same as the range of the original function, so the range is 
Yes it is a function, it passes the straight line test
Answer:
C: x^4+6x^3-12x-72
Step-by-step explanation:
For the function : f(x)=√x^2+12x+36
It can be factorized to
f(x)=√(x+6)²
=x+6
f(x)*g(x)
=(x+6)(x^3-12)
Expand the brackets
=x^4-12x+6x^3-72
rearrange the numbers
x^4+6x^3-12x-72
