Each equation given below describes a parabola. Which statement best compares their graphs? X=2y^2 X=8y^2 A. Both parabolas open upward, and x=8y^2 is wider than x=2y^2.
B. Both parabolas open upwards, and x=2y^2 is wider than x=8y^2.
C. Both parabolas open to the right, and x=8y^2 is wider than x=2y^2.
D. Both parabolas open to the right, and x=2y^2 is wider than x=8y^2.

D)Both parabolas open to the right, and is wider than

Step-by-step explanation:

Standard equation of parabola :

If a < 0, then the parabola open downwards and if a > 0, then the parabola open upwards.

If a < 0, then the parabola open left and if a > 0, then the parabola opens right

Given equations : and

and

in both the equations a>0

So, Both parabolas are open to the right.

Refer the attached graph

--- blue

So, is wider than

So, Option D is true

answer: the value of x is 7cm

step-by-step explanation:

the answer is y = 11.54

hope this : )
