HELP :) Find the Domain and Range of the following Relation.(Add 1 space after your domain answer)

1. {(3,5), (4,15), (5,20), (6,25), (7,30)
2. {(-1,2), (-1,4), (-1,6), (-1,8), (-1,10)}
3. {(-6,1), (-5,0), (-4,-1), (-3,-2), (-2,-3)}

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
