Answer:
No it isn't.
Step-by-step explanation:
A function gives just one
y
for every
x
.
In this case there will always be two
y
's for every
x
, because the reverse will be
y
=
+
√
x
or
y
=
−
√
x
Example:
x
=
4
→
y
=
−
2
or
y
=
+
2
Answer : option B
Given: center (4,2), vertex (9,2), and focus (4+2sqrt5,2)
The distance between vertex and center is 9-4 = 5
Center is (h,k) so h= 4 and k =2
focus is (h+c,k)
From the given focus (4+2sqrt5,2), c= 2sqrt(5)
Standard form of equation is

h= 4, k=2, a=5, c=2sqrt(5), we need to find out b




b^2 = 5
plug in all the values


Option B is correct
The point slope form of the line is:
D. y+4=2/5(x+7)
