Question

f(n) = 3n. Find a value for the independent variable if the dependent variable has a value of 1. 3 1 -3

Answer 1

independent variable is n
the dependent variable is f(n) since the answer of f(n) depends on what the value of n is.

so plug in 1 for f(n) and solve for n

1 = 3n
1/3 = 3n/3
n = 1/3

hope this helped!
