Answer:
y² = -12x.
Step-by-step explanation:
Given : Parabola with vertex (0,0) and focus (-3,0).
To find : Which is the equation of Parabola.
Solution : We have given that vertex (0,0) and focus (-3,0).
Standard form of parabolic equation (y - k)² = 4p (x - h).
where the focus is (h + p, k) and vertex (h,k)
We can see h= 0 , k = 0,
h+p = -3
0 + p = -3
p = -3.
On plugging the values of h , k ,p
Then equation of parabola (y - 0)² = 4(-3) (x - 0).
y² = -12x.
Therefore, y² = -12x.
Answer:
slope = 3, point = (6, -2)
Step-by-step explanation:
This is in point-slope form which looks like this : y-y1 = m(x-x1).
m is the slope, an x1 and y1 are the x and y coordinates of the point. Remember to flip the sign of the numbers for the points i.e. the y+2 in the equation becomes -2 for the point.
Option C:
A triangle that does not have the same dimension as one of the sides of pyramid.
Because....
There is a rectangular Pyramid, which is sliced perpendicular to its base and through its vertex.
The domain of a function is the set of all acceptable input values (X-values). The range of a function is the set of all output values (Y-values).
