Answer:
C
Step-by-step explanation:
Firstly, we know that the function must be negative due to its shape. This means that the answer cannot be B
Next we can use the equation that is used in order to find the vertex of the parabola.
A)
As the vertex is at x=3 on the graph, this one could be a contender.
C)
This also could be the equation
D)
This rules option D out.
For this last step, we can look at where the zeroes would be for each equation. (These values are irrational, so we cannot look at specific number)
A)
As this equation has a negative value for c, this means that one zero must be positive and the other must be negative.
This means that option A can be ruled out
C)
As this equation has a positive value for c, this means that both of the zeroes must be positive. This means that it is the only one that fits all of the criteria.
Given number is 78/14.
We have to find two whole numbers between which given number 78/14 lies.
Let's convert that into mixed fraction.
To do that we divide 78 by 14 to find the quotient.
We see that 14 goes 5 times into 78 and leaves remainder of 8.
So we can rewrite 78/14 as .
means little more than 5 but less than 6.
So required two whole numbers are 5 and 6.
