Answer:
<em></em>
Step-by-step explanation:
Functions have independet variables(the value of the variable could be any number, we have no restrictions) and dependent variaariables(the values of this variables depends of idependent variables)
the problem says that <em>x</em> is the independent variable, so we say that <em>y</em> is a dependent variable. Dependent need to be replaced by funcion notation, in this case we use <em>y=f(x)</em>
So we raplace it in the equation and we have:
<em></em>
we solve for <em>f(x)</em> passing <em>-6x</em> and <em>-9</em> to the right side and changing the signs, and we get:
