The statement of Gabriella, “The graph will not have an inverse function.” is incorrect. Option B is correct.
Let us understand about the given graph:
The given graph is a graph of a cube root function.
So, the statement of Noelle, “The graph represents the function ." is correct.
So, option A is not correct.
The inverse of a cube root function is a cubic function.
So, the statement of Gabriella, “The graph will not have an inverse function.” is incorrect.
So, option B is correct.
The domain and range of the cube root function are all real numbers.
So, the statement of Julian, “The domain and range of the function is all real numbers.” is correct.
So, option C is not correct.
From the graph, we can see f(-1) = -1.
So, the statement of Yemen, “The value of f(-1) = -1.” is correct.
So, option D is not correct.
Thus, the statement of Gabriella, “The graph will not have an inverse function.” is incorrect. Option B is correct.

Step-by-step explanation:
The diagram showing the three pieces of paper of three digit in which two of the letters were covered can be seen below.
From the diagram; we have;
243 , 1_7 , _26
Assuming the covered digits are _
The sum is 826.
i.e
243 + 1_7 + _26 = 826
The objective is to determine the sum of the two unknown digits
So; we need to think about what number can we add put in 1_7 to determine the covered digit in _26
From ; 1_7 , we have the choice to pick from 0 - 9
Assuming the covered digit is 0; let's check if we are right
So; 243 + 1<u>0</u>7 + _26 = 826
350 + _26 = 826
_26 = 826 - 350
_26 = 476
So; the covered digit is in the position of 4 , but it doesn't tally together
i.e 426 is not the same as 476, which makes our assumption to be wrong.
Let consider the covered digit to be 5 for example.
So; 243 + 1<u>5</u>7 + _26 = 826
400 + _26 = 826
_26 = 826 - 400
_26 = 426
The covered digit is in the position of 4
SO;
<u>4</u>26 = 426
Here , our assumption is right.
As such , the covered digits are 5 and 4
The sum of the two covered digits are = 5 + 4 = 9
