The equation of the ellipse is required \frac{(x)^2}{16} +\frac{(y+4)^2}{25}=1

The required equation is

\frac{x^2}{16} +\frac{(y+4)^2}{25}=1

It can be seen that the major axis is parallel to the y axis.

The major axis points are

(h,k+a)=(0,1)\\(h,k-a)=(0,-9)\\k+a=1\\k-a=-9

Subtracting the equations

2a=10\\\implies a=5

The foci are

(h,k+c)=(0,-1)\\(h,k-c)=(0,-7)

k+c=-1\\k-c=-7

Subtracting the equations

2c=6

c=3

k+c=-1 implies that k=-1-c

k=-1-3

k=-4

<h3>What is the equation of the ellipse?</h3>

\frac{(x-h)^2}{b^2} +\frac{(x-h)^2}{a^2}=1

So we get,

\frac{(x-0)^2}{4^2} +\frac{(y+4)^2}{5^2}=1

\frac{(x)^2}{16} +\frac{(y+4)^2}{25}=1

Therefore the equation is, \frac{(x)^2}{16} +\frac{(y+4)^2}{25}=1.

Soloha48 [4]
No x-intercept/zero

Step by step

To find x-intercept/zero, substitute f(x)=0

F(x)=-20

0=-20

The statement is false for any value of

X=0

Since there is no solution for f(x)=0, there is no -intercept/Zero

Your welcome:)
