The $35 per month function represents your total gym cost for one month of domain restrictions.
$8 Per Class
f(x,f) = 35x+8f x, f ≥ 0
N IV Here x ерresent months.
f represents no- of classes.
The three functions with limited domains are the square root function, the logarithm function, and the reciprocal function.
The domain of f (x) = x2 - 6 is also because f (x) is defined for all real numbers x. However, some functions are not defined for all real numbers, so they are evaluated in a limited range. For example, the domain of f(x) = cannot take the square root of a negative number.
Domain restrictions allow you to create functions defined through numbers to create functions that are fit for purpose. A piecewise-defined function is a composition of multiple functions with non-overlapping domain constraints. Some functions are restricted to values that make them undefined.
