Answer:

A. {−3.5, −2, 1, 2.5}

Step-by-step explanation:

Remember that the range is the possible values for Y in any given function, so in this case, we are given the Y values and we have to solve the function for x:

y=9+6x

6x=y-9

[tex]x=\frac{y-9}{6}[/tex]

So we just insert the values, the first one being -12.

[tex]x=\frac{y-9}{6}\\x=\frac{-21}{6}\\x=\frac{-12-9}{6}\\x=-3.5[/tex]

So since from the options only A has -3.5 as an option that's the correct answer.
