Answer:
B
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = x² + 7 ( subtract 7 from both sides )
y - 7 = x² ( take the square root of both sides )
± = x
Change y back into terms of x, thus
(x) = ±

Two fractions given are 5/7 and 1/13
We will first calculate each of the fraction and then we will decide which one is greater and which one is smaller accordingly we will assign the symbol for the same.
First we will find the answer for 5/7.
Now dividing the number 5 from 7 we get;
Now we will find the answer for 1/13
Now dividing the number 1 from 13 we get;
From above we can see that 0.714 is greater than 0.076.
Hence we can say that 5/7 is greater than 1/13.
So the symbol used will be greater than > where number 5/7 is greater than 1/13
5/7 > 1/13
