Question

11 fewer than a number f

Answer 1

11 fewer than a number f would be algebraically:

f-11

"f" though is usually a function, such as f(x) which is used to calculate a number corresponding to a given value of x.

f(x)-11 might be appropriate.

Let f(x) =x which is the same as y=x, just a simple function.

then f(x)-11 is a graphically a straight line with y intercept =-11 and slope = 1

f is the output, the dependent variable. x is the input, the independent variable, measured on the horizontal axis. f is measured on the vertical axis or y axis.
