The independent variable of f(c) = -3c + 9 is c
What are variables?
Variables in an equation are the unknown parameters of the equation that change in values
There are two types of variables
- Dependent variable
- Independent variable
How to determine the independent variable?
The equation of the function is given as
f(c) = -3c + 9
The dependent variable is the output of the function, while the independent variable is the input of the function
For the function, f(c) = -3c + 9
The input variable is c
Hence, the independent variable of f(c) = -3c + 9 is c
