Is a 3.86 weighted gpa good for freshman year of highschool? I am in 4 honors classes, 1 AP, and 2 standard. Keep in mind this is not on the 4.0 scale(unweighted) and is weighted.

x:       y:  

-1         4

0         4

1         6

2         18

3         20  

answer is a.

13.268

hope you get it right.

the equation of the parabola is y2=12x

explanation:

the vertex is midway between the focus ad the directrix

so, the vertex is (0,0)

let p=(x,y) be a point on the parabola.

the distance of p from the directrix is equal to the distance from the focus.

x+3=√(x−3)2+(y−0)2

(x+3)2=(x−3)2+y2

x2+6x+9=x2−6x+9+y2

y2=12x

graph{y^2=12x [-10, 10, -5, 5]}
