Is the relation a function? Why or why not? {(3, –1), (3, 0), (–3, 4), (3, 8)}

No; the relation passes the vertical line test.

No; three range values exist for domain value 3.

Yes; only one range value exists for each domain value.

Yes; three range values exist for domain value 3.

the answer is 45 i just did it on oddesy ware

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
