Answer:
vertex:(2,-4)
Focus:(2,- )
Axis of symmetry :x=2
Directrixt: y=-
Step-by-step explanation:
Since both y’s are negative you can combine them to make -6y=1 then you divide -6 on each Side to get y=6
Answer:
A
Step-by-step explanation:
A dilation changes the size by a select factor.
Answer:
b = -6
Step-by-step explanation:
Apply the exponent rule that
In this case,
Set that equal to :
Apply the exponent rule that so now you get:
Since the base is y for both sides of the equation, just set the exponents equal to each other and solve for b.
4b = -24
divide each side by 4 to get:
b = -6
<u>Answer:</u>
<u>Step-by-step explanation:</u>
Equation of parabola with focus at (0,-4) and directrix is .
We know that parabola is the locus of all the points such that the distance from fixed point on the parabola to fixed line directrix is the same.
The parabola is opening downwards.
Let any point on parabola is (x,y).
Distance from focus(0,-4) to (x,y) =
