The is a factor that's affected by changes in the independent variable

Answer 1

Dependent variable.......

Answer 2

So we want to know what factor is affected by the changes of the independant variable. So if we have the form f(x)=x, x would be the independant variable and when we change the value of that variable we directly change the dependant variable, because the value of the dependant variable is dependant of the independant variable.
