Answer:
stretched by a factor of 2, reflected over the y-axis, and translated 9 units left
Step-by-step explanation:
The given function is 
We can rewrite this function by factoring -4 in the radicand to get:

We further simplify the square root of 4 to get:

The parent function is 
When we compare to the parent function, there is a stretch by a factor of 2, reflection over the y-axis, and translation 9 units left
The last option is correct
Answer:
9 inches
Step-by-step explanation:
Diameter=D
Radius=R
D=(2)R
(18)=(2)R
18/2=2/2 R
9=R
I all of those options are true
