Answer:
C
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = E(- 2, 2) and (x₂, y₂ ) = F(4, - 6)
EF =

Given
Required
True values of x
We have:
Collect like terms
Divide both sides by 3
This means that x has a value lesser than 14.67.
Hence, the valid values are:
A parabola is open up if a > 0.
The vertex formula:
(h; k) - the coordinates of the vertex
Therefore h = -5 < 0
Answer: B. y = x² + 10x + 24.
