What is the range of the function?
(1,2) (2,4) (3,9) (4,16)

range ={ 2,4,9,16}

Step-by-step explanation:

range is  related to y coordinate of the points

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
