Answer:
option 4. The graph has zeroes at x = 15 an x = -15 and it opens upward.
Step-by-step explanation:
we have

This is the equation of a vertical parabola open upward (the leading coefficient is positive)
The vertex represent a minimum
The vertex is the point (0,-225)
The axis of symmetry is x=0 (y-axis)
Find the x-intercepts (values of x when the value of y is equal to zero)
For y=0

square root both sides

therefore
The graph has zeroes at x = 15 an x = -15 and it opens upward.
X cannot be 6 or -2/5 because if they were the denominator would be zero
The tenths place is right after the decimal point. So, 3160.9903 can be 3160.9.
Ratio 5:2 as fraction should be 5/2
as you know 5/2 = 2.5
This is the biggest compared to 9/5, 8/5 and 2/7
9/5 < 2
8/5 <2
2/7 < 1
so 5/2 is greatest
