Math Algebra 8.2.1.1

1. f(x) = 4x + 4. In the equation above, which variable is the dependent variable and which is the independent variable?

2. f(x) = 5x. In the equation above, if the independent variable’s coefficient is doubled, what will the effect be on the dependent variable?

3. y = 14x + 3 – 5. In the equation above, what is the value of the constant?

4. f(x) = 4x + 8. If the dependent variable in the equation above is equal to 8, what is the independent variable equal to?
