I think it is the third one. If it’s not the third one then it’s the first one.
Answer:
The x-intercepts are
(x1,y1)=(4,0)
(x2,y2)=(6,0)
Step-by-step explanation:
we know that
The equation of the given parabola is

we have
the vertex is the point (5,-4)
substitute

The y-intercept is the point (0,96)
substitute and solve for a



The equation of the vertical parabola is equal to

Find the x-intercepts
Remember that
The x-intercepts are the values of x when the value of y is equal to zero
For y=0

Simplify

Rewrite

square root both sides




therefore
The x-intercepts are
(x1,y1)=(4,0)
(x2,y2)=(6,0)
To figure this out you would need to create a rectangle with dimensions that give you an area of 7 ft.². The easiest example would be a rectangle that is one by seven. If the scale is 1:16, that means for every foot it is actually representing 16 feet. The actual length and width would be found by multiplying 1×16 and 7×16. The true dimensions then would be 16 x 112. Multiply this together to get a total area of 1792 ft.².
The x intercepts must be 1 and -4, so C.
