I don't get this, need some help, examples and information
The linear function $f$ is given by $$f(x) = 3x - 2 ,\quad -2 \leq x \leq 4.$$
Enter the independent variable and the dependent variable.
Determine the function values $f (-2)$, $f (-1)$, $f (0)$ and $f (4)$.
Enter the definitions and values crowd.
I know what a function is, but how can you find the independent variable and the dependent variable?
How one can determines the function values and how you specify the definitions and values crowd?
What I know about functions:
Variables can have any name, $x$, $y$, $z$, or "maria", "girl", "young"; at a specific value and function can be called anything.
My own example of functions:
Age = 18
year = 6
Maria (age, years) = age + years = 24
in 6 years Maria is going be 24 years
