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

---- Red

--- blue

So, is wider than

So, Option D is true

positive

step-by-step explanation:

the quadrant is facing upwards

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
