The equation t^2=a^2 shows the relationship between a planets orbital period, t, and the planets mean distance from the sun, a, in astronomical units, au,. If the orbital period of planet y is twice the orbital period of planet x, by what factor is the mean distance increased?

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

look at the picture i have filled out a table for it. hope this .

391.6 is the correct answer
