Just count, its really simple...its hard to explain using a keyboard tho...sorry i wasnt much help
In order to be continuous everywhere, we only need to satisfy continuity at
. For that to happen, we need to have

By the function's definition,
. Compute the limits:


So we must have

The wind is traveling 675 miles in 3 hours bc u times 450×3 which is 1350 and divide that by 2
The answer is 7.57 of what they make for each year
Because the focus is (-2,-2) and the directrix is y = -4, the vertex is (-2,-3).
Consider an arbitrary point (x,y) on the parabola.
The square of the distance between the focus and P is
(y+2)² + (x+2)²
The square of the distance from the point to the directrix is
(y+4)²
Therefore
(y+4)² = (y+2)² + (x+2)²
y² + 8y + 16 = y² + 4y + 4 + (x+2)²
4y = (x+2)² - 12
y = (1/4)(x+2)² - 3
