The answer is true.
Method 1:
The given function is a cubic function. And inverse of a cubic function is also a function.
Method 2:
Since the function is one-to-one function i.e it passes the horizontal line test, its function will pass the vertical line test which is a test if a relation is a function or not.
So, yes the inverse of G(x) will be a function.
The positive square root of 35
= 5.9160797831 because 5.9160797831^2 is 35
Therefore you multiply 5.9160797831 to 5.9160797831
A counterexample is an example that disproves a conclusion. For this problem all you have to do is make a list of numbers that are less than zero. Your counterexample could be something like: -1, -1.5, -2, -2.5, -3, -3.5
