Answer :

yes, this is because whatever x is, y equals 9x+1 and so since x is in a function the formula describes y as a function of x

sorry if this is wrong, i tried

Answer with explanation:

We are given a equation in terms of variable x and y as:

                     [tex]y=9x+1[/tex]

      Yes, this formula describes y as a function of x.

Since, the value of y could be obtained corresponding to each value of x by using this formula.This means that x is the input or the independent variable and the y is the output or the dependent variable which depends on x.

y is a function of x means that it vary according to the change in x.
