Answer:
the vertex of the parabola is:(-2,0)
the focus of the parabola is:(-2,
)
the directrix of the parabola is:y=
Step-by-step explanation:
we know that for any general equation of the parabola of the type 
the vertex of the parabola is given by (h,k)
where 
and 
therefore by the given data we have h=-2 and k=0
hence vertex=(-2,0)
the general equation of the parabola of the type 
; the parabola symmetric around the y-axis has the focus from the centre i.e. the vertex (h,k) at a distance a as (h,k+a) and the directrix is given by y=k-a
so focus is 
now the directrix of the parabola is 
.
The new length should be 9.5 inches and the new width should be 7 inches.
Zeros: Where the parabola crosses the x-axis.
Vertex: The turning point of the parabola.
AOS: The x-value where the turning point is.

<u>Answer </u>
B. f(x) = - (y/x)⁵
<u>Explanation</u>
A negative power means the reciprocal of that number raised to the positive value .
For example, a⁻ⁿ = 1/aⁿ
So, for the question above.
f(x) = -(x/y)⁻⁵
= - 1/(x/y)⁵
= - (y/x)⁵
