3. find the range of values of x for which x^2 – 3x + 8 has values between 6 and
12.
( draw the number line for the inequalities too)
pls a lot of brainliest rewarded
first correct ans will be marked as top ans

1) letter c.

2) 4 square root of 9

hope this

step-by-step explanation:

idk what your asking for but the sum equals 13

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]}
