Answer:

Given that,

[tex]f(x)=-7x-2[/tex]

To find the inputs when the output is -3 ​

that is, when f(x)=-3, to find the value of x

Put f(x)=-3 in the above equation we get,

[tex]-3=-7x-2[/tex][tex]-7x=-3+2[/tex][tex]\begin{gathered} -7x=-1 \\ x=\frac{1}{7} \end{gathered}[/tex]

Answer is: x=1/7.
