Answer 13

You'll get used to it with more practice. Remember that f(x) is just another way to say "what is the value of the function at x?" And the function is defined as "y," so it's the same as saying "What is the value of y at x?" Just always keep in mind the variables can change (it's not always going to be "x" and "y") but what they stand for is always the same.

Well, of x and y, which one is the independent variable and which one is the dependent variable?

Answer 21

it is the number on the right of the thing

Answer 22

of the first number

Answer 23

The value of y DEPENDS on what x is. So we say that y is the dependent variable, and x is the independent variable.As x changes, y changes. So if you are looking for the independent variables, look for the x's
